Yes, it would mean that.
And while I was never sure this would be a good thing to do in any case
now, I had already almost convinced myself against it anyway, as while the
example in question (something like)
would be reasonably easy to handle (find the '}' ignore the rest, and
just mark it as a bad expansion, to generate an error if it was ever used)
other cases like perhaps
are a lot trickier to figure out what to do with, without actually
understanding what is supposed to be happening (nb: I just made that
example up from nowhere, I have no idea if anything like that could ever
actually occur - but nor do I know it could not - which is the point.)
I think we can consider this question answered.
