The urge to have basic language features not be part of the language, but instead be part of the standard library is responsible for a lot of the less than stellar parts of of C++. Std::move/forward are particularly obvious cases, but you get similar accessing members of tuples, etc. Wanting to keep things in the standard library rather than the language itself means that you have to compile large amounts of template hell for a wide array of basic things which hurts build time even in debug modes, and then as this article says you end up with no-op operations that become calls. You also can’t easily debug any of this because you end up with absurd layers of template nonsense for what is again basic functionality. You can compile with -O1, but that then inlines things that aren’t part of the standard library that makes debugging of the actually relevant code annoying (this is what the debug llvm and clang debug builds do), as it inlines your own code and also means that you lose variables all over the place.
