The rule I liked best is "ignore callables, descriptors, and anything 
with leading & trailing double underscores". Personally I'd modify that 
to simply "anything with two leading underscores" so you can have 
private variables.  It seems Pythonic to me in that classes already 
treat all those things special.  And if you want enums of any of those 
things you can instantiate & insert them by hand after the class definition.

Does that fail in an important way?
