Indeed it is. I guess my only innovation is realizing that you don't
have to create a real metaclass -- you can set __metaclass__ to a
function that does the magic. I like your feature of refusing
overrides unless flagged with @replace.

I think that despite the objection that monkeypatching shoudn't be
made too easy, it's worth at looking into a unification of the API,
features, and implementation.
