I think that's a brilliant idea. David and Peter, logistics aside, what do you think of (or how to you feel about) this suggestion? Or, if not a complete merger, unifying everything that is desired in the standard library. The code not included (e.g. EUI/MAC address stuff, vendor lookups, etc.) could continue its existence as a project, using the stdlib as a basis... d _______________________________________________ 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
