24 ECMA Section: 15.2.4.3 Object.prototype.valueOf()
26 Description: As a rule, the valueOf method for an object simply
27 returns the object; but if the object is a "wrapper"
28 for a host object, as may perhaps be created by the
29 Object constructor, then the contained host object
32 This only covers native objects.
