Ooof. restrict keyword enters the chat. C and C++ are two languages that evolve together, but one is not a superset of the other.

I see this comment a lot, but it's not true (at least not any more). Many valid C programs do not compile through the C++ compiler. The standards for C++ and C have deviated over the years.

lots of good examples of why this is wrong here: https://floooh.github.io/2019/09/27/modern-c-for-cpp-peeps.h...

Ironically your comment it's the ignorant one. Try compiling a large C codebase with g++.
