for / while else doesn't make sense

My objection is not to the choice of keyword, it’s to the whole design of the loop construct.

It turns out C-style for-loops “for (init; test; incr) ...” are very versatile. If my loop has more than one exit, I use the endless form “for (;;)” and do an explicit “break” for every exit condition.

Also, they let me declare a variable that is scoped to the loop, that is initialized just once before the loop starts, e.g.

    for (int loopvar = initial_value;;)
      {
        if (loopvar == limit)
            break;
        ... processing ...
        if (found_what_im_looking_for)
            break;
        ++loopvar;
      } /*for*/

I wish I could do this in Python...
