Every single time there is a link about C/C++, I do a quick "Ctrl+F Rust", and every single time there is some rant about "but Rust is safer than C".

Every. Single. Time.

This article is about a new Clang extension:

> An exciting feature just landed in the main branch of the Clang compiler. Using the [[clang::musttail]] or __attribute__((musttail)) statement attributes, you can now get guaranteed tail calls in C, C++, and Objective-C.

(literally the first line of the article)

What does Rust have to do with this? Nothing.

Does the author suggest that you should only use C for high performance? No.
