I don't think anyone's arguing the opposite. What I *am* seeing argued
is if it's the only correct way to do it, and that anyone who does it
any other way is a scoundrel and a knave. ;-)
For what it's worth, most of my loops run to completion, with no sign of
a break anywhere. Some have a break, and use it. Some, even, (dare I
say it?) use break *and* else! And it's awesome! Go Python! :-D
