  It's possible you're one of the two kinds of "C/C++ programmers" and so you've assumed that since this is how C prefers to introduce things it must be how C++ does it too, but not so. C++ 20 introduced concepts. In C++ 17 "concept" is a perfectly reasonable name for an identifier. Maybe it's a class, a variable, a free function, all fine. In C++ 20 that's a reserved word and can't be used as an identifier. Rust does not have this problem, a 2015 function named "await" is somewhat annoying to use from Rust 2018 or later where "await" is a keyword, but it's only annoying it isn't actually difficult.
