OK, so I'd say the filtering would follow any changes made to some_seq - not because it's a documented guarantee as such, but simply as a consequence of the behaviour of generators and closures. I'd tend to steer clear of code that relied on that behaviour in practice, as I think it's likely to be hard to understand/maintain, but I'm aware that reality's never quite that simple :-) Paul -- https://mail.python.org/mailman/listinfo/python-list
