Zig has extensive metaprogramming support. For SIMD I'm using ispc which is a shader-like language/compiler from Intel. You write your code from the point of view of a single SIMD lane and the compiler takes care of the rest. Intel kind of screwed the project over with their stupid naming and terrible website but it's a very cool project. I take the resulting object file and link it with the rest of the project. This is very different from trusting a compiler to vectorize your code, with a shading language you know it's going to vectorize. What's absolutely brilliant is when you start to use divergent control flow and see how well it handles it. https://pharr.org/matt/blog/2018/04/18/ispc-origins.html https://pharr.org/matt/blog/2018/04/18/ispc-origins.html
