You are using the same generic example -- it does show the issue you are concerned with, but offers no rational for why we should "fix" it -- in other words, we cannot tell if it's actually broken.

Please provide an example of code you are actually using -- a trimmed down metaclass is fine, but it should show the kinds of names you are changing to, why you want to change the names, etc.

Maybe this is a just a documentation issue, or maybe it's an overlooked case that should be supported in Python -- we cannot tell based solely on your generic example.
