I suppose it could lazily materialise a list behind the scenes when needed (i.e. on the first __getitem__ or __len__ call), but the semantics still wouldn't be *exactly* the same, as it wouldn't be possible to iterate over it more than once. Also as any side-effects would be delayed. -- 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/archive%40mail-archive.com
