i am really just trying to come up to speed in ruby. i was wondering how
a natural idiom for "separating mechanism and policy" would look in
python. in another post someone wrote a really short version using
"break" in a block... i didn't know this was possible and is pretty much
what i was looking for.

the world of internal iterators is just a little different from the
external ones in python. but after spending a little more time with
ruby, finding the Generator module and being told that you can "break"
within a module (although i haven't quite grasped how that fits in with
the closure concept!?) i am a lot more comfortable with internal
iterators...

idioms take a long to time to learn, comprehend and apply...

thx,
