    Huh, you're right.

    Apparently it's still considered experimental (even thought apparently Google uses it in production) so it's not in the User Manual. There's this: https://github.com/sbcl/sbcl/blob/master/doc/internals-notes...

    As a side note, I executed the lisp code to validate the results and the methods I ported to C# using SBCL and apparently a function was missing so I added it and provided an updated lisp version in my repo here.

    Indeed, it's newish (from this summer https://github.com/sbcl/sbcl/releases/tag/sbcl-2.5.6) and mainly thanks to C. Zhang's work.

    In Grad School I started with an "AI in Lisp Textbook" (which was still the most common at the time in the late oughts, I hear many have moved to Python since) and searched for a Common Lisp interpreter that felt right. I think I ended up with SBCL [0], but this was obviously a while back so my memory is slippery about it.

    (The professor I had for that AI course in Grad School didn't know Lisp and wanted to learn it better, especially because so much of the textbook was in it, so asked us for volunteers to learn it as well and I took that as an excuse/challenge to do every project with a language choice that semester in Common Lisp.)

  • Which Lisp? Beginner

    Oversimplifying, there are three big variants: Common Lisp, Scheme, Clojure. Each of them has a lot of somewhat similar implementations:

    * Clojure: A lot of support for immutable data. It runs in the JVM so you will have a lot of the libraries you are use to. Probably the best option for you. https://clojure.org/

    * Scheme, in particular Racket: Mostly functional, and in particular Racket has a lot of support to make your own variant. This is the option I prefer but I have to disclaim it's a biased recommendation. https://racket-lang.org/

    * Common Lisp: I heard a lot of good things about SBCL, in particular to add anotations to make the code faster https://www.sbcl.org/

    > why this language is so special

    Macros, everyone use macros, too many at the beginning, but a few where they are really necessary later.
