@@ -9,3 +9,5 @@ Only use:
 * Never use `arguments` directly without `.length` or `[i]`.
 * STRICTLY `fn.apply(y, arguments)` is ok, nothing else is, e.g. `.slice`, That's because `Function#apply` is special.
 * Be aware that adding properties to functions (e.g. `fn.$inject =...`) and bound functions (i.e. the result of `Function#bind`) generate hidden classes and, therefore, are not safe when using `.apply`.

+If you need to manipulate `arguments`, use a copy. [sliced](https://github.com/aheckmann/sliced) is a good tiny library for this purpose.
