Clang 16 as used by clang-tidy-16 does not support C++23, C++2c, and C++26.

I have been considering to move to clang-tidy-17, but that gives other issues, which I'm still investigating.

Fair point, probably not. I think we could even remove 0x, 1y. 1z, and 2a. Since we don't support that ancient compilers.

AFAIK there is no gcc yet that support C++26, but as @jwakely indicated it's expected that GCC will support C++26 and C++2c at the same time.
