Why can't we always use getattr_static? If there's a reason for not using it always, please describe that in a comment.

This is related to my latest comment. Sorry, I didn't make this clear:

getattr_static(...,'__class__') returns <attribute '__class__' of 'object' objects> whereas getattr would return <class '__main__.Foo'>. What should getmembers return? Using getattr_static for every attribute doesn't seem to be the solution. It works fine with methods, functions and properties, but some edge cases seem to require getattr (such as __class__). It is not clear what the expected behaviour is.

Got it, well, describe this in a comment :)

value = getattr_static(object, key)
else:
value = getattr(object, key)
# handle the duplicate key
if key in processed:
raise AttributeError
