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'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.

like this that can actually no longer be saved.

 There is way more code written in C than C++.  For instance, just about all real time systems such as device and engine management are written in C.

These days, I believe engine management code is more likely to be written in C++.

 One of my friends writes the device code for a NAS manufacturer.  The code starts off with:
    while (1)
    {
       ...  a bunch of code
    }
 

Hey!  He's copied from me!
Pretty much /every/ embedded system has that loop at its heart - either once (for bare metal), or in the RTOS and also once per thread.
