Here are some gc crates:

https://docs.rs/rsgc/latest/rsgc/

https://docs.rs/ristretto_gc/latest/ristretto_gc/

https://docs.rs/dumpster/latest/dumpster/

https://docs.rs/shredder/latest/shredder/

I have no experience with them. In any case, it would be advisable to make the GC implementation swappable so that the language is gc-implementation-agnostic.

The hope of the experiments is to hopefully find an API that can be used and allow for the GCs to be more swappable. At least that's my personal hope.

We really have to dig into the experimentation and rewrite before knowing for certain.
