Corrupt Function String Representation

Function.prototype.toString provides a string representation of the code the given function. In Aran, the instrumented code will be returned rather than the original code. Note that the exact format of this code the representation is not part of the ECMAScript specification and is not guaranteed to be stable across different JavaScript engines anyway. The only requirement is that if two functions have the same source code then they should share source code representation as well. Unfortunately, this is not always the case in Aran because of compilation variables. So the below assertions is not guaranteed to hold after Aran instrumentation.

console.assert(function () {}.toString() === function () {}.toString());
