    ECMA Section:       15.2.4.3 Object.prototype.valueOf()

    Description:        As a rule, the valueOf method for an object simply
                        returns the object; but if the object is a "wrapper"
                        for a host object, as may perhaps be created by the
                        Object constructor, then the contained host object
                        should be returned.

                        This only covers native objects.
