As much as I'd like to get a simple generic implementation into functools, the lack of support for ABCs still bothers me (despite my last post about that on the tracker item). I'd be a -0 on it going in as is, but if someone can figure out a clever way of supporting ABCs without completing killing the invocation speed for generics, that would go up to a +1. (The current difficulty of this may actually reflect a more significant limitation on the available metadata for ABCs in PEP 3119: it is easy to ask "is this specific type an example of this ABC?", but difficult to ask "which ABCs is this type as example of?". For actual inheritance, the __mro__ attribute means that both questions are easy to answer, but I'm not aware of any corresponding way of answering the latter question for ABCs) Cheers, Nick. P.S. I just unassigned myself from that tracker item - I'm going to have my hands full working on the proposed change to the with statement. -- Nick Coghlan | ncogh...@gmail.com | Brisbane, Australia --------------------------------------------------------------- _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
