a typical use-case for for-in-else is a search loop:

    for item in collection:
        if predicate(item):
            print "found", item
            break
    else:
        print "not found"
        return

    print "use", item

where your "abnormal behaviour" is, of course, the expected
behaviour.  if you insist on looking at things the wrong way,
things will look reversed.
