Why is changing an exception more acceptable than creating a new one? (I don't have a strong opinion either way, but I'd like some reasoning; Jack's approach at least doesn't break code.) Especially if the new exception isn't "public" (in the builtins with other exceptions). -- Aahz ([EMAIL PROTECTED]) <*> http://www.pythoncraft.com/ "The joy of coding Python should be in seeing short, concise, readable classes that express a lot of action in a small amount of clear code -- not in reams of trivial code that bores the reader to death." --GvR _______________________________________________ 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
