That's an excellent idea! > It's just a question of which one is easier to explain. I think the function-definition-time one is easiest to both explain and also to reason about when writing code, since definition time is well-defined, whereas "the first time it's executed" is somewhat fuzzy. It's also a lot clearer how it interacts with closures, which is another good point. I recommend adding this option to the relevant PEP (whichever it is). -- Greg _______________________________________________ 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
