+/**
+ * This {@code WeakMap} emulation is observably equivalent to the
+ * ES-Harmony WeakMap, but with leakier garbage collection properties.
+ *
+ * <p>As with true WeakMaps, in this emulation, a key does not
+ * retain maps indexed by that key and (crucially) a map does not
+ * retain the keys it indexes. A map by itself also does not retain
+ * the values associated with that map.
+ *
+ * <p>However, the values associated with a key in some map are
+ * retained so long as that key is retained and those associations are
+ * not overridden. For example, when used to support membranes, all
+ * values exported from a given membrane will live for the lifetime
+ * they would have had in the absence of an interposed membrane. Even
+ * when the membrane is revoked, all objects that would have been
+ * reachable in the absence of revocation will still be reachable, as
+ * far as the GC can tell, even though they will no longer be relevant
+ * to ongoing computation.
+ *
+ * <p>The API implemented here is approximately the API as implemented
+ * in FF6.0a1 and agreed to by MarkM, Andreas Gal, and Dave Herman,
+ * rather than the offially approved proposal page. TODO(erights):
+ * upgrade the ecmascript WeakMap proposal page to explain this API
+ * change and present to EcmaScript committee for their approval.
+ *
+ * <p>The first difference between the emulation here and that in
+ * FF6.0a1 is the presence of non enumerable {@code get___, has___,
+ * set___, and delete___} methods on WeakMap instances to represent
+ * what would be the hidden internal properties of a primitive
+ * implementation. Whereas the FF6.0a1 WeakMap.prototype methods
+ * require their {@code this} to be a genuine WeakMap instance (i.e.,
+ * an object of {@code [[Class]]} "WeakMap}), since there is nothing
+ * unforgeable about the pseudo-internal method names used here,
+ * nothing prevents these emulated prototype methods from being
+ * applied to non-WeakMaps with pseudo-internal methods of the same
+ * names.
+ *
+ * <p>Another difference is that our emulated {@code
+ * WeakMap.prototype} is not itself a WeakMap. A problem with the
+ * current FF6.0a1 API is that WeakMap.prototype is itself a WeakMap
+ * providing ambient mutability and an ambient communications
+ * channel. Thus, if a WeakMap is already present and has this
+ * problem, repairES5.js wraps it in a safe wrappper in order to
+ * prevent access to this channel. (See
+ * PATCH_MUTABLE_FROZEN_WEAKMAP_PROTO in repairES5.js).

+   * Security depends on HIDDEN_NAME being both <i>unguessable</i> and

+   * <p>Given the known weaknesses of Math.random() on existing
+   * browsers, it does not generate unguessability we can be confident
+   * of.
+   *
+   * <p>It is the monkey patching logic in this file that is intended
+   * to ensure undiscoverability. The basic idea is that there are
+   * three fundamental means of discovering properties of an object:
+   * The for/in loop, Object.keys(), and Object.getOwnPropertyNames(),
+   * as well as some proposed ES6 extensions that appear on our
+   * whitelist. The first two only discover enumerable properties, and
+   * we only use HIDDEN_NAME to name a non-enumerable property, so the
+   * only remaining threat should be getOwnPropertyNames and some
+   * proposed ES6 extensions that appear on our whitelist. We monkey
+   * patch them to remove HIDDEN_NAME from the list of properties they
+   * returns.
+   *
+   * <p>TODO(erights): On a platform with built-in Proxies, proxies
+   * could be used to trap and thereby discover the HIDDEN_NAME, so we
+   * need to monkey patch Proxy.create, Proxy.createFunction, etc, in
+   * order to wrap the provided handler with the real handler which
+   * filters out all traps using HIDDEN_NAME.
+   *
+   * <p>TODO(erights): Revisit Mike Stay's suggestion that we use an
+   * encapsulated function at a not-necessarily-secret name, which
+   * uses the Stiegler shared-state rights amplification pattern to
+   * reveal the associated value only to the WeakMap in which this key
+   * is associated with that value. Since only the key retains the
+   * function, the function can also remember the key without causing
+   * leakage of the key, so this doesn't violate our general gc
+   * goals. In addition, because the name need not be a guarded
+   * secret, we could efficiently handle cross-frame frozen keys.

-/**
- * This {@code WeakMap} emulation is observably equivalent to the
- * ES-Harmony WeakMap, but with leakier garbage collection properties.
- *
- * <p>As with true WeakMaps, in this emulation, a key does not
- * retain maps indexed by that key and (crucially) a map does not
- * retain the keys it indexes. A map by itself also does not retain
- * the values associated with that map.
- *
- * <p>However, the values associated with a key in some map are
- * retained so long as that key is retained and those associations are
- * not overridden. For example, when used to support membranes, all
- * values exported from a given membrane will live for the lifetime
- * they would have had in the absence of an interposed membrane. Even
- * when the membrane is revoked, all objects that would have been
- * reachable in the absence of revocation will still be reachable, as
- * far as the GC can tell, even though they will no longer be relevant
- * to ongoing computation.
- *
- * <p>The API implemented here is approximately the API as implemented
- * in FF6.0a1 and agreed to by MarkM, Andreas Gal, and Dave Herman,
- * rather than the offially approved proposal page. TODO(erights):
- * upgrade the ecmascript WeakMap proposal page to explain this API
- * change and present to EcmaScript committee for their approval.
- *
- * <p>The first difference between the emulation here and that in
- * FF6.0a1 is the presence of non enumerable {@code get___, has___,
- * set___, and delete___} methods on WeakMap instances to represent
- * what would be the hidden internal properties of a primitive
- * implementation. Whereas the FF6.0a1 WeakMap.prototype methods
- * require their {@code this} to be a genuine WeakMap instance (i.e.,
- * an object of {@code [[Class]]} "WeakMap}), since there is nothing
- * unforgeable about the pseudo-internal method names used here,
- * nothing prevents these emulated prototype methods from being
- * applied to non-WeakMaps with pseudo-internal methods of the same
- * names.
- *
- * <p>Another difference is that our emulated {@code
- * WeakMap.prototype} is not itself a WeakMap. A problem with the
- * current FF6.0a1 API is that WeakMap.prototype is itself a WeakMap
- * providing ambient mutability and an ambient communications
- * channel. Thus, if a WeakMap is already present and has this
- * problem, repairES5.js wraps it in a safe wrappper in order to
- * prevent access to this channel. (See
- * PATCH_MUTABLE_FROZEN_WEAKMAP_PROTO in repairES5.js).

-   * <p>TODO(erights): On a platform with built-in Proxies, proxies

-   * uses the Stiegler shared-state rights amplification pattern to
-   * reveal the associated value only to the WeakMap in which this key
-   * is associated with that value. Since only the key retains the
-   * function, the function can also remember the key without causing
-   * leakage of the key, so this doesn't violate our general gc
-   * goals. In addition, because the name need not be a guarded

-   * <p>To treat objects as identity-keys with reasonable efficiency
-   * on ES5 by itself (i.e., without any object-keyed collections), we
-   * need to add a hidden property to such key objects when we
-   * can. This raises several issues:
-   * <ul>
-   * <li>Arranging to add this property to objects before we lose the
-   *     chance, and
-   * <li>Hiding the existence of this new property from most
-   *     JavaScript code.
-   * <li>Preventing <i>certification theft</i>, where one object is
-   *     created falsely claiming to be the key of an association
-   *     actually keyed by another object.
-   * <li>Preventing <i>value theft</i>, where untrusted code with
-   *     access to a key object but not a weak map nevertheless
-   *     obtains access to the value associated with that key in that
-   *     weak map.
-   * </ul>
-   * We do so by
-   * <ul>
-   * <li>Making the name of the hidden property unguessable, so "[]"
-   *     indexing, which we cannot intercept, cannot be used to access
-   *     a property without knowing the name.
-   * <li>Making the hidden property non-enumerable, so we need not
-   *     worry about for-in loops or {@code Object.keys},
-   * <li>monkey patching those reflective methods that would
-   *     prevent extensions, to add this hidden property first,
-   * <li>monkey patching those methods that would reveal this
-   *     hidden property.
-   * </ul>
-   * Unfortunately, because of same-origin iframes, we cannot reliably
-   * add this hidden property before an object becomes
-   * non-extensible. Instead, if we encounter a non-extensible object
-   * without a hidden record that we can detect (whether or not it has
-   * a hidden record stored under a name secret to us), then we just
-   * use the key object itself to represent its identity in a brute
-   * force leaky map stored in the weak map, losing all the advantages
-   * of weakness for these.

- * API difference with jQuery version:
- * - No optional boolean (true -> deep extend) first argument,
- *   use `extendFlat` for first-level only extend and
- *   use `extendDeep` for a deep extend.
- *
- * Other differences with jQuery version:
- * - Uses a modern (and faster) isPlainObject routine.
- * - Expected to work with object {} and array [] arguments only.
- * - Does not check for circular structure.

-// The function below is called when constructing a cwise function object, and does the following:
-// A function object is constructed which accepts as argument a compilation function and returns another function.
-// It is this other function that is eventually returned by createThunk, and this function is the one that actually
-// checks whether a certain pattern of arguments has already been used before and compiles new loops as needed.
-// The compilation passed to the first function object is used for compiling new functions.
-// Once this function object is created, it is called with compile as argument, where the first argument of compile
-// is bound to "proc" (essentially containing a preprocessed version of the user arguments to cwise).
-// So createThunk roughly works like this:
-// function createThunk(proc) {
-//   var thunk = function(compileBound) {
-//     var CACHED = {}

+/**
+ * This {@code WeakMap} emulation is observably equivalent to the
+ * ES-Harmony WeakMap, but with leakier garbage collection properties.
+ *
+ * <p>As with true WeakMaps, in this emulation, a key does not
+ * retain maps indexed by that key and (crucially) a map does not
+ * retain the keys it indexes. A map by itself also does not retain
+ * the values associated with that map.
+ *
+ * <p>However, the values associated with a key in some map are
+ * retained so long as that key is retained and those associations are
+ * not overridden. For example, when used to support membranes, all
+ * values exported from a given membrane will live for the lifetime
+ * they would have had in the absence of an interposed membrane. Even
+ * when the membrane is revoked, all objects that would have been
+ * reachable in the absence of revocation will still be reachable, as
+ * far as the GC can tell, even though they will no longer be relevant
+ * to ongoing computation.
+ *
+ * <p>The API implemented here is approximately the API as implemented
+ * in FF6.0a1 and agreed to by MarkM, Andreas Gal, and Dave Herman,
+ * rather than the offially approved proposal page. TODO(erights):
+ * upgrade the ecmascript WeakMap proposal page to explain this API
+ * change and present to EcmaScript committee for their approval.
+ *
+ * <p>The first difference between the emulation here and that in
+ * FF6.0a1 is the presence of non enumerable {@code get___, has___,
+ * set___, and delete___} methods on WeakMap instances to represent
+ * what would be the hidden internal properties of a primitive
+ * implementation. Whereas the FF6.0a1 WeakMap.prototype methods
+ * require their {@code this} to be a genuine WeakMap instance (i.e.,
+ * an object of {@code [[Class]]} "WeakMap}), since there is nothing
+ * unforgeable about the pseudo-internal method names used here,
+ * nothing prevents these emulated prototype methods from being
+ * applied to non-WeakMaps with pseudo-internal methods of the same
+ * names.
+ *
+ * <p>Another difference is that our emulated {@code
+ * WeakMap.prototype} is not itself a WeakMap. A problem with the
+ * current FF6.0a1 API is that WeakMap.prototype is itself a WeakMap
+ * providing ambient mutability and an ambient communications
+ * channel. Thus, if a WeakMap is already present and has this
+ * problem, repairES5.js wraps it in a safe wrappper in order to
+ * prevent access to this channel. (See
+ * PATCH_MUTABLE_FROZEN_WEAKMAP_PROTO in repairES5.js).

+   * <p>TODO(erights): On a platform with built-in Proxies, proxies

+   * uses the Stiegler shared-state rights amplification pattern to
+   * reveal the associated value only to the WeakMap in which this key
+   * is associated with that value. Since only the key retains the
+   * function, the function can also remember the key without causing
+   * leakage of the key, so this doesn't violate our general gc

+   * <li>Arranging to add this property to objects before we lose the
+   *     chance, and
+   * <li>Hiding the existence of this new property from most
+   *     JavaScript code.
+   * <li>Preventing <i>certification theft</i>, where one object is
+   *     created falsely claiming to be the key of an association
+   *     actually keyed by another object.
+   * <li>Preventing <i>value theft</i>, where untrusted code with
+   *     access to a key object but not a weak map nevertheless
+   *     obtains access to the value associated with that key in that
+   *     weak map.
+   * </ul>
+   * We do so by
+   * <ul>
+   * <li>Making the name of the hidden property unguessable, so "[]"
+   *     indexing, which we cannot intercept, cannot be used to access
+   *     a property without knowing the name.
+   * <li>Making the hidden property non-enumerable, so we need not
+   *     worry about for-in loops or {@code Object.keys},
+   * <li>monkey patching those reflective methods that would
+   *     prevent extensions, to add this hidden property first,
+   * <li>monkey patching those methods that would reveal this
+   *     hidden property.
+   * </ul>
+   * Unfortunately, because of same-origin iframes, we cannot reliably
+   * add this hidden property before an object becomes
+   * non-extensible. Instead, if we encounter a non-extensible object
+   * without a hidden record that we can detect (whether or not it has
+   * a hidden record stored under a name secret to us), then we just
+   * use the key object itself to represent its identity in a brute
+   * force leaky map stored in the weak map, losing all the advantages
+   * of weakness for these.

-/**
- * This {@code WeakMap} emulation is observably equivalent to the
- * ES-Harmony WeakMap, but with leakier garbage collection properties.
- *
- * <p>As with true WeakMaps, in this emulation, a key does not
- * retain maps indexed by that key and (crucially) a map does not
- * retain the keys it indexes. A map by itself also does not retain
- * the values associated with that map.
- *
- * <p>However, the values associated with a key in some map are
- * retained so long as that key is retained and those associations are
- * not overridden. For example, when used to support membranes, all
- * values exported from a given membrane will live for the lifetime
- * they would have had in the absence of an interposed membrane. Even
- * when the membrane is revoked, all objects that would have been
- * reachable in the absence of revocation will still be reachable, as
- * far as the GC can tell, even though they will no longer be relevant
- * to ongoing computation.
- *
- * <p>The API implemented here is approximately the API as implemented
- * in FF6.0a1 and agreed to by MarkM, Andreas Gal, and Dave Herman,
- * rather than the offially approved proposal page. TODO(erights):
- * upgrade the ecmascript WeakMap proposal page to explain this API
- * change and present to EcmaScript committee for their approval.
- *
- * <p>The first difference between the emulation here and that in
- * FF6.0a1 is the presence of non enumerable {@code get___, has___,
- * set___, and delete___} methods on WeakMap instances to represent
- * what would be the hidden internal properties of a primitive
- * implementation. Whereas the FF6.0a1 WeakMap.prototype methods
- * require their {@code this} to be a genuine WeakMap instance (i.e.,
- * an object of {@code [[Class]]} "WeakMap}), since there is nothing
- * unforgeable about the pseudo-internal method names used here,
- * nothing prevents these emulated prototype methods from being
- * applied to non-WeakMaps with pseudo-internal methods of the same
- * names.
- *
- * <p>Another difference is that our emulated {@code
- * WeakMap.prototype} is not itself a WeakMap. A problem with the
- * current FF6.0a1 API is that WeakMap.prototype is itself a WeakMap
- * providing ambient mutability and an ambient communications
- * channel. Thus, if a WeakMap is already present and has this
- * problem, repairES5.js wraps it in a safe wrappper in order to
- * prevent access to this channel. (See
- * PATCH_MUTABLE_FROZEN_WEAKMAP_PROTO in repairES5.js).

-   * patch them to remove HIDDEN_NAME from the list of properties they
-   * returns.

-   * <p>TODO(erights): On a platform with built-in Proxies, proxies

-   * filters out all traps using HIDDEN_NAME.

-   * <p>TODO(erights): Revisit Mike Stay's suggestion that we use an
-   * encapsulated function at a not-necessarily-secret name, which
-   * uses the Stiegler shared-state rights amplification pattern to
-   * reveal the associated value only to the WeakMap in which this key
-   * is associated with that value. Since only the key retains the
-   * function, the function can also remember the key without causing
-   * leakage of the key, so this doesn't violate our general gc
-   * goals. In addition, because the name need not be a guarded

- * Inspired by https://github.com/justmoon/node-extend/blob/master/index.js
- * All credit to the jQuery authors for perfecting this amazing utility.
- *
- * API difference with jQuery version:
- * - No optional boolean (true -> deep extend) first argument,
- *   use `extendFlat` for first-level only extend and
- *   use `extendDeep` for a deep extend.
- *
- * Other differences with jQuery version:
- * - Uses a modern (and faster) isPlainObject routine.
- * - Expected to work with object {} and array [] arguments only.
- * - Does not check for circular structure.
- *   FYI: jQuery only does a check across one level.
