I can't help thinking that most of this confusion is caused by using < for determining subsets. If < were not defined for sets and people had to use "set.issubset" (which exists already), then sorting a list with sets would raise an exception, a much more understandable failure mode than getting back a list in arbitrary order.
Personally I think it was premature to throw out __cmp__. What should have happened instead is for __cmp__ to be augmented with a fourth outcome, "not equal but unordered". Then operations such as sorting that require a total ordering could use __cmp__ and complain if they get an unordered result. -- 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
