New submission from Ryan McCampbell: Is there a reason register() doesn't check for abstract methods, like subclassing does? Would it fail for some builtin classes? It seems that this would be a better guarantee that, say, something really is iterable when you check isinstance(Collections.Iterable, o), since someone could have called Collections.Iterable.register(o.__class__) without adding an __iter__ method to their class.
