.inherited(sub) ⇒ Object

Let's try to keep things clean, in case methods have been added to Object either directly or through an included module. We'll do this whenever a class is derived from BasicObject Ideally, we'd do this by trapping Object.method_added and M.method_added for any module M included in Object or a submodule Seems really though to get right, but pull requests welcome ;-)
