If I understand you, I don't think I like this idea. It
adds complexity to the mental model of a loop. "The
loop variable disappears when the loop ends unless the
loop contains a break".
In my opinion, Python should pick a model and stick to
it. Loop variables are either ordinary variables that
exist until you explicitly delete them, or they are
special variables that automagically disappear at the
end of the loop. I vote for the first one.
