   4     ECMA Section:       15.5.4.2 String.prototype.toString()
   5
   6     Description:        Returns this string value.  Note that, for a String
   7                         object, the toString() method happens to return the same
   8                         thing as the valueOf() method.
   9
  10                         The toString function is not generic; it generates a
  11                         runtime error if its this value is not a String object.
  12                         Therefore it connot be transferred to the other kinds of
  13                         objects for use as a method.
