To reiterate what Tim already pointed out, that original usecase
required a way to feed values *into* the comprehension.

There's no need for dedicated syntax for that if we can just set an
variable and have it show up in the comprehension.
Yes, but doing it that way also allows things to come *out*
of the comprehension, which is something we previously thought
was such a bad idea that we went to considerable lengths to
stop it happening. Now we seem to be seriously considering
going to further lengths to allow it again for *some* things.
Seems to me we should have a pretty compelling reason for
doing that. I don't feel very compelled by what I've seen
so far.
