(In reply to Jakub Jelinek from comment #10)
> That again is completely valid in C2X.

Yes, it is. And again, it's still something worth diagnosing (IMO) because it's
utter nonsense code that is invalid with C17 and earlier as well as C++.

I don't believe WG14 intended to make this invalid code valid for C2x.
