Just for the record, I thought Nathaniel's NotImplemented suggestion was a good one, and his explanation of why, was clear and convincing, but he's already accepted the alternative, of a custom error, so I don't think there's much point on going back over that. Also just for the record, I'd like to warmly thank y'all for your great patience in this long discussion.
