Enum already is callable - it creates Enum subclasses.

e.g.

Color = Enum("Color", ("RED", "GREEN", "BLUE"))

(or something similar, I didn't check the docs.)

In general, it sounds to me like you already can avoid them becoming
members if you want - simply by making them a property. Therefore,
letting them be members by default doesn't sound weird to me.

As for embedded classes - well, the cannot be subclasses because the
outer class is not instantiated. You could perhaps build a class
decorator that injects the outer class in the inner class' MRO, but
that doesn't sound like code I'd want to debug.
