Have you tried using ranges with latest clang? That's a pretty central part of C++20 and it doesn't work.

Have you tried converting iterations to SIMD and using vector extension to target x86, ARM, Webassembly and compile for Linux/Windows/MacOS with a simple piece of code? It's a pretty significant speed up and it only work with Clang.

What does that have to do with standards support?

None of that is part of ISO C++ compliance.

How is ISO C++ compliance relevant to actual development?

For many places it is quite relevant when choosing official compiler toolchains.

By the way, nice way of creating a throwaway account for the anti-ISO posts all over the place.

> Ranges [are] pretty central part of C++20 Just shows how distant the committee is from the developers.
