Wait, that's not the way I would expect else to work. You (and and it would 
seem python) would have the else clause run if the loop is terminated by 
the for/foreach rater than a break/goto. I would expect that the else clause 
would be executed if the loop is terminated before the first iteration.

I think your expectation would be a good feature but I can't really see else 
being the right keyword to use. How about "finally"? Or another option with 
scope(*) like "fallthrough"?
