What does this new syntax give us that we don't already have with this?
for x in y
if x in c:
some_op(x)
I think it's really the equivalent of
for x in y:
if not x in c:
break
do_stuff
which to me give the proposed syntax a bit more relative strength.
I'm probably +0 -- but I do like comprehension syntax, and have often wanted a "side effect" comprehension:
$ side_effect(item) for item in an_iterable if condition(item) $
(using $ 'cause there aren't any more brackets ...)
rather than having to write:
for item in an_iterable:
if condition(item):
side_effect(item)
To the point where I sometimes write the list comp and ignore the generated list. NOt too huge a burden to cretae. list of None and throw it away, but it feels wrong ;-)
