And one can do this oneself. Faced with
while True:
stuff_required_to_make_the_decision()
if the_decision():
break
other_stuff()
Wrapping the `stuff_required_...` and `the_decision` up into a generator
would simplify the statement, and if it were done well the code overall
would probably be better.
