The most interesting Clojure-like language around is, IMO, Carp[^1]. Carp is a Lisp written in Haskell that compiles down to C with Rust ownership semantics and looks like Clojure. So you get a GC-less Lisp with fast startup time that is suitable for game development with the safety guarantees of Rust.
It doesn't seem to have immutable data structures by default and concurrency primitives. That changes greatly how you write algorithms and structure your program.
It's cool, but it's like the complete opposite of the main ideas behind Clojure.
I thought about including this since I saw a talk about it once where the guy referenced Clojure, but they don't talk about Clojure at all in the README.md.
