  24     ECMA Section:       15.5.4.2 String.prototype.toString()
  25
  26     Description:        Returns this string value.  Note that, for a String
  27                         object, the toString() method happens to return the same
  28                         thing as the valueOf() method.
  29
  30                         The toString function is not generic; it generates a
  31                         runtime error if its this value is not a String object.
  32                         Therefore it connot be transferred to the other kinds of
  33                         objects for use as a method.
