Some containers become temporarily immutable during iteration. This includes
dicts, sets, and collections.deque. Their implementation is equally simple

So, if a list is extended during iteration, the iterator will continue through
the new items. If it shrinks to a point before the most recent iteration,
then no further items are available and the length is reported at zero.
