/**
   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).
