I seem to remember we've been here before. I'll be disappointed if I have to wrap every for-loop that I write in a with-statement on the offchance that it might be using a generator that needs finalisation in order to avoid leaking memory. I'm becoming more and more convinced that we desperately need something better than __del__ methods to do finalisation. A garbage collector that can't be relied upon to collect garbage is simply not acceptable. -- 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
