While we're nitpicking :-) NotImplemented is the singleton returned (not
raised) by numeric methods (like __add__) and rich comparision methods
(__eq__ and friends) to indicate they don't handle the combination of
objects passed to them (see section 3.2 of the Language Reference). What
you want here is NotImplementedError (which is a subclass of Exception).
