   3     Corresponds To:     15.5.4.3-3-n.js
   4     ECMA Section:       15.5.4.3 String.prototype.valueOf()
   5
   6     Description:        Returns this string value.
   7
   8                         The valueOf function is not generic; it generates a
   9                         runtime error if its this value is not a String object.
  10                         Therefore it connot be transferred to the other kinds of
  11                         objects for use as a method.
