The stdlib needs a modernization much more than the language, unlike 'C the language', 'C the stdlib' is still stuck deep in the K&R era (together with POSIX).

The stdlib needs a modernization much more than the language, unlike 'C the language', 'C the stdlib' is still stuck deep in the K&R era (together with POSIX). For a different language syntax it makes a lot more sense to consider using a different language in the first place though, because everybody has a different opinion what such a 'better C' syntax should look like (e.g. it sounds like you'd actually want Zig).
