One way to do this is to iterate backwards over the list:
for index in xrange(len(list), 0, -1):
w = list[index]
That way you aren't trying to touch things after the POP, only before.
Of course, it kind of depends on exactly what your overall goal is, as
to wether there's a better way to do it.
This problem is something that iterators should address, but I don't
know what you have to do to get a list to be iteratorable.
