IIUIR, Clojure uses the JVM garbage collector to clean up memory.

How does Jank do this whilst keeping the user code… still Clojure?

Jank uses Boehm GC (written in C, also used by the likes of Inkscape, Guile and Mono) - it is discussed a little in the previous blog posts, e.g. https://jank-lang.org/blog/2023-07-08-object-model/

Guile seems to prepare to switch to https://github.com/wingo/whippet - a GC C library that can wrap Boehm/BDW but also provides more (and less) advanced GC options. Should be a good option for Jank and similar projects as well - especially if they already use BDW.

Have you considered MPS? https://github.com/Ravenbrook/mps .

I'm just an enthusiastic bystander so I don't know the answer. Hopefully Jeaye can chime in.

Yep! MPS was considered, but Boehm was significantly easier to get going. For jank's next GC, the plan is to use MMTK.
