no, it seems as though you're either misrepresenting my position or you misunderstood what I said. I said that there wasn't a use-case for explicitly pulling that functionality out into a a new class, and having 6 classes. > But it seems to me that this is exactly what you have in the > current implementation, except you call it a Network object, and have > rejected the suggestion that the non-network bits of the address should > be zeroed. I have not rejected this.

But your hostile attitude isn't making it easy. apologies if you find me hostile. I'm not sure how you'd expect me to be if, after 2 months 200+ messages, both on list and off, you were unable to recall a single use-case. > -- > Steven D'Aprano > _______________________________________________ > 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/python-dev%40hda3.com > _______________________________________________ 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
