  24     ECMA Section:       15.2.4.2 Object.prototype.toString()
  25
  26     Description:        When the toString method is called, the following
  27                         steps are taken:
  28                         1.  Get the [[Class]] property of this object
  29                         2.  Call ToString( Result(1) )
  30                         3.  Compute a string value by concatenating the three
  31                             strings "[object " + Result(2) + "]"
  32                         4.  Return Result(3).
