/**
File Name: 15.2.4.2.js
ECMA Section: 15.2.4.2 Object.prototype.toString()
Description: When the toString method is called, the following
steps are taken:
1. Get the [[Class]] property of this object
2. Call ToString( Result(1) )
3. Compute a string value by concatenating the three
strings "[object " + Result(2) + "]"
4. Return Result(3).
