anyway I don't bother.
Surely it would not be "elif break", but "elif not break"?
To me, anything beginning with "else" or "elif" suggests an
alternative branch, not an additional one (YMMV):
if condition:
do_something
else:
do_something_completely_different
Therefore I would find "if not break" or even "and if not break" more
intuitive.

Whenever I've used the for-else, I've put a # no-break right next to
it, to
remind myself as much as anyone else.
for...: not break: is the best alternative I've yet seen,
congrats. Perhaps in
Python 5 it can be enabled, with for-else: used instead for empty
iterables, as
that's what I expected the first few dozen times.
For empty iterables, how about "elif None:"? :-)
