The same can be said about Zig's comptime. It's entirely unlike anything C, C++ or Rust has to offer.

While it's possible to translate C to Zig code - and you don't need an LLM for that, it's a Zig compiler/build-system feature - the result will be quite different from a project that's developed in Zig from the ground up since the translation output wouldn't make use of Zig's unique features (and Zig isn't really unique as 'C translation target', C can also be translated to unsafe Rust, or even to Javascript - see early Emscripten versions).

Also, the 'C compatibility' of Zig is implemented via a separate compiler frontend, Rust toolchains could do exactly the same thing by integrating the Clang frontend into the Rust compiler.
