python lets you do this:

    for v in ...:
        if v == ...:
           break
    else:
        atend

So the else part is executed should the loop terminate normally (no break is
executed or the loop body is never entered).

It can be applied to while loops too.

I'm not sure whether it's a great idea but it did save a 'match' variable
when I was trying to match one 'condition' in a list of 'conditions'.
