On the sync version of a class, in a particular place in the code, I correctly get an UnboundLocalError.
However, on the async version of the class, in the exact same "place" in the code, it incorrectly raises an AttributeError for the generator class as shown below
> if await self.address(name) == address_:
E AttributeError: attribute 'address_' of 'setup_address_AsyncENS_gen' undefined
