I did something very similar to this myself. My GC implementation was pretty heavily inspired by manishearth's Rust GC. My swing at the Crafting Intepreters in Rust can be found here: https://github.com/mwerezak/sphinx-lang https://github.com/mwerezak/sphinx-lang Although, at the time I was really interested in Lua's syntax so for extra credit I designed a completely different syntax for Lox closer to Lua's. I'd love to revisit this project sometime and implement a register-based VM similar to Lua's.
