So it'll have to wait till Python 4000. ;-) (Still, that approach is in some ways actually better than the current approach: you don't need a __prepare__, for example. Actually, if one were designing a class creation protocol from scratch today, it would probably be simplest to borrow the __enter__/__exit__ protocol, with __enter__() returning the namespace to be used for the suite body, and __exit__() returning a finished class... or something similar. Python-ideas stuff, to be sure, but it could likely be made a whole lot simpler than the current multitude of hooks, counter-hooks, and extended hooks.)
