Left some suggestions. Can you also check the build failures?

Maybe also mention in the error message that the metaclass is not supported with a native class?

Let me separate this out to its own PR. Right now is_implicit_extension_class (in mypyc/irbuild/util.py) just returns True/False. To print a nice message we would have to go through each individual check in is_implicit_extension_class and make a nice user-facing message.
It is very good feedback, and I agree with you, just think it can be split out to separate PR.
