Yes, we would have to do that. object->iter relationships work because the reference is only from the iter back; we don't try to reuse iters as we would views. Weak refernces work. Okay, perhaps parasite views should be handed out by a callable after all instead of saying "hey, reuse this reference here." It would actually be more compatable with what we do, and fit better with the situation where a views would be created on the fly (slices?) - Adam > > -- > Greg > > _______________________________________________ > Python-3000 mailing list > Python-3000@python.org > http://mail.python.org/mailman/listinfo/python-3000 > Unsubscribe: > http://mail.python.org/mailman/options/python-3000/adam.deprince%40gmail.com _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
