In other words, everything as it is today, only with different
implementations under the hood. :-)

Rolling back around to the original point, I don't see any reason to ban
[x for x in thing], changing current practice, when it is so easy to keep
it. [(x for x in thing)] is also current practice (perhaps "bad style" in
some sense, but definately possible in 2.4), and I don't think there is a
good reason to change that, either.
