/**
   File Name:          string-002.js
   Corresponds To:     15.5.4.3-3-n.js
   ECMA Section:       15.5.4.3 String.prototype.valueOf()

   Description:        Returns this string value.

   The valueOf function is not generic; it generates a
   runtime error if its this value is not a String object.
   Therefore it connot be transferred to the other kinds of
   objects for use as a method.
