Very interesting. I note that virtually no Python developers were aware this worked, according to the PEP. Well, then at least I don't feel quite so silly! But if it's going away in Python 3, not worth the trouble in any case; it could just conceivably have been worth hacking, but not if Python in general is going the other way - if only to reduce confusion.
