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...
