/**
    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.
