+# TODO
+
+* Tests
+* Test for `"use strict"` directive in function not being moved up to outside `with ()`
+* Test for multiple `with ()`s between var and its binding
+* Test for `with ()` with no `{}` statement block
+* Tests for `with` in `eval()`
+* Tests for `this` where implicitly used by `super()` and `super`
+
+* Fix proxy preventing correct `this` being passed to method calls
+
+This prints 'true' in original, but 'false' once instrumented:
+
+```js
+const obj = {
+  foo() {
+    console.log(this === obj);
+  }
+};
+with (obj) {
+  foo();
+}
+```
+
+This should print '1,2,3' but prints '[object Undefined]':
+
+```js
+with ([1, 2, 3]) {
+  console.log(toString());
+}
+```
+
+Also affects primitives:
+
+```js
+with (123) {
+  console.log(toString());
+}
+```
+
+Should print '123', but instead throws error. The proxy that `with` expression is replaced with is passed to `Number.prototype.toString` as `this` and it throws `TypeError: Number.prototype.toString requires that 'this' be a Number`.
+
+* Raise Github issue for interaction with const violations
+
+e.g. How to deal with this? Whether `x = 2` is a const violation depends on whether `obj` has a property called `x` or not.
+
+```js
+const x = 1;
+with (obj) {
+  module.exports = () => { x = 2; };
+}
+```
