Its a hobby project, its not nearly done, don't use it in production.

But, that said, that is basically what it is: https://github.com/clojit

I would love to write a JIT for it, but currently its a half done interpreter. You compile Clojure to Bytecode (of our own design, see clojit-doc) and a C interpreter (we started in Rust but the pre 1.0 chances and some other stuff killed that).

All of this is inspired by LuaJit, specifically my goal is to work on a tracing compiler. It just takes to much time to get there.
