  🌵 Cycle-Aware Reference Counting in Rust

  

  Absolutely. I have seen some pretty cool concepts in Rust for memory cleanup; not just garbage collection, but deterministic reference cycle removal by cactusref. And the fun thing about these is that you still get all of Rust's zero-cost abstractions and epic modern language design.

  A fast, small, safe, gradually typed embeddable scripting language derived from Lua

  

  Roblox's Luau (now open-source) is a great example of GC taken to the absolute extreme. They have a small performance overview available which summarizes some of the optimizations they've implemented. They are very heavily invested into making Luau as fast as it can possibly be. Which makes sense, given how it's used on the platform.
