43 ECMA Section: 15.2.4.3 Object.prototype.valueOf()
45 Description: As a rule, the valueOf method for an object simply
46 returns the object; but if the object is a "wrapper"
47 for a host object, as may perhaps be created by the
48 Object constructor, then the contained host object
51 This only covers native objects.
