In an attempt to bring some topicality to the group, has anyone started using, or considering, C23 ?  There's quite a lot of change in it, especially compared to the minor changes in C17.

 I like that it tidies up a lot of old stuff - it is neater to have things like "bool", "static_assert", etc., as part of the language rather than needing a half-dozen includes for such basic stuff.
 I like that it standardises a several useful extensions that have been in gcc and clang (and possibly other compilers) for many years.
 I'm not sure it will make a big difference to my own programming - when I want "typeof" or "chk_add()", I already use them in gcc.  But for people restricted to standard C, there's more new to enjoy.  And I prefer to use standard syntax when possible.
 "constexpr" is something I think I will find helpful, in at least some circumstances.

I am waiting MSVC support. There are a lot of simple features MSVC could implement and deliver in small increments. But it is very slow.
I am would use today if I had.
  - #warning
  - [[nodiscard]]
  - typeof
  - digit separators
  - bool true, false
I am not planning to use:
  - enum with specific types.
  - #elifdef
  - nullptr
  - auto
  - constexpr
Not sure
  - empty initializer
