If you are interested in this, you might also be interested to learn that I also got clojure running on SBCL via OpenLDK. See https://github.com/atgreen/cl-clojure.

Regarding LLM-usage, the bulk of OpenLDK was written without the use of LLMs. But recently I let Claude loose on the code to fix a few remaining problems blocking kawa. Claude also upleveled the Java support from Java 8 to Java 21.

I wrote a couple of blog entries related to this work that might be of interest. One was around how I had to use the MOP to optimize method dispatch in CLOS for clojure: https://atgreen.github.io/repl-yell/posts/clos-mop-dispatch/
