Oh, I agree it shouldn’t reference the typing module. But it should not raise NameError. This whole thing already is a special case. We can debate what else it should, e.g. skip the name, return a fixed error token, return an error token that includes the name that failed (this is part if the NameError), return a string, etc…
FWIW the “tiny” change to decorator syntax looks untenable.
