first observed in gcc 13.2 (however, i could not find anything in git bisect
history that would suggest post-2020 that this would work)
I get that gnu2x is "experimental and incomplete", but it really does seem like
something specific is broken at that point that should be
documented...somewhere, and this represents an actual
bug/not-yet-working-functionality thing
