 Oh, I thought C23 used '_', since Python uses that. I prefer single quote as that is not shifted on my keyboard. (My language projects just allow both!)

C++ uses single quotes - it is much more natural for C to copy C++ than to copy Python.

 That fact that it is not widespread is a problem however, so I can't use either without restricting the compilers that can be used.
 For example gcc 14.x on Windows accepts it with -std=c23 only; gcc on WSL doesn't; tcc doesn't.
 

Surprisingly enough, this new C23 feature is only available when using C23 or later.
