That is what the 'else' suggests to me - particularly with 'while'
loops. I don't think I've ever needed the existing 'else', but I could
have used a loop-body-not-executed-at-all special case on a number of
occasions

I can see the use an application of 'else', of course - if you use
'break' to end a loop you may need different cleanup and therefore
need to skip the standard cleanup. But if this is an issue I'm
probably already using raise rather than break because it's most
likely an error rather than a normal case.

My guess is that it probably made a lot more sense before exceptions
were added to Python.
