Sure, but Guido already invoked EIBTI. For one (obscure) alternative, Type[A, B] reminded me of Fun(A,B) (the functors from category A to category B), and in Python I would tend to map that to a function type (taking argument from A, returning value from B). Another (probably more plausible to Pythonistas) would be a type that *mixes* A and B, ie, one might be reminded of class C(A, B): pass isinstance(obj, C) or even (continuing the example) class E(B, A, D): # Order of A, B irrelevant! Yikes! pass isinstance(obj, (C, E)) Regards, _______________________________________________ Python-Dev mailing list [email protected] https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
