Avoiding duplicated code always trumps an uneasy feeling that
the code might not be as pretty as it could be in another
language or with new language constructs...

Once you get over that uneasy feeling, and implement the loop
that way a few times, and focus on maintainability, you'll
probably stop worrying about it.  At least, I did. :)
