Hi everyone,
PEP 7 says that C code should conform to C89 with a subset of C99 allowed.
It's 2021 and all the major compilers support C11 (ignoring the optional
parts).
C11 has support for thread locals, static asserts, and anonymous structs
and unions. All useful features.
Is there a good reason not to start using C11 now?
Depends on compiler support. I would say that if clang, gcc, and MSVC all support it then we should consider switching, but if any of them are lagging we would need to find the common base line (hence why the subset of C99 when we last talked about this).
