  24     ECMA Section:       15.5.4.3 String.prototype.valueOf()
  25
  26     Description:        Returns this string value.
  27
  28                         The valueOf function is not generic; it generates a
  29                         runtime error if its this value is not a String object.
  30                         Therefore it connot be transferred to the other kinds of
  31                         objects for use as a method.
