Looks like someone needs to read the `iter` docs :)

Hi,

This time I'm posting on the right list :) Sorry for the mistake in the
last thread.

`iter` has a very cool `sentinel` argument. I suggest an additional
argument `sentinel_exception`; when it's supplied, instead of waiting for a
sentinel value, we wait for a sentinel exception to be raised, and then the
iteration is finished.

This'll be useful to construct things like this:

     my_iterator = iter(my_deque.popleft, IndexError)

Before starting discussion about the new parameter:
how passing 'my_deque.popleft' is supposed to work?
