Yep, and it's obviously possible to do that now with just function decorators.
Getting my head around what that actually *does* is a little trickier, though
(as near as I can tell, it will register a standalone function named __call__,
with nothing linking it to the containing class).
What a class decorator allows is the registration of the whole process of
invoking the metaclass and hence __new__ and __init__ as a single unit.
Anyway, I don't particularly feel the lack of class decorators, but I thought I
should mention this (perhaps small) category of non-transforming decorators as a
situation where class decoration would make more sense to me than using a metaclass.
Cheers,
Nick.
