I've been thinking about this too, and I think it's reasonable to let the metaclass provide the dict to be used as locals. [snip] class C(B1, B2, metaclass=Foo):

If there's to be a special syntax for this, I don't think it should have the word "metaclass" in it -- it's too verbose and too jargony.

How about

class C(B1, B2) is M: ...

This is concise, keeps the metaclass clearly separated from the list of bases, and avoids creating any new keywords.
