I like this idea. I believe Rust does something somewhat similar (though not quite) for processing compile-time procedural macros. We see somewhat similar, but external approaches in the Clojure ecosystem with Babashka and Joker (and probably a few others).

In general, I like this, but not every language actually needs it. Like, what would that even be in Python for example?

Something for PyPy perhaps? JITs written in the host language are the original use case I was thinking of, but that’s not the sole domain where it applies.
