/**
    File Name:          boolean-001.js
    Description:        Corresponds to ecma/Boolean/15.6.4.2-4-n.js

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