/**
    File Name:          string-001.js
    Corresponds To:     15.5.4.2-2-n.js
    ECMA Section:       15.5.4.2 String.prototype.toString()

    Description:        Returns this string value.  Note that, for a String
                        object, the toString() method happens to return the same
                        thing as the valueOf() method.

                        The toString 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.
