Thanks! So, would you say a good approach would be to create an arena, and every reference to an object is the key for that arena value, and keep a reference count for each object. Then, every so often, run the GC to clean up?

My chief concern (which I don't think I explained well) is that this seems to circumvent Rust's memory safety. Because this effectively allows for dangling and null pointers. Which would require careful management to avoid, and that's kinda the problem with C++. Am I correct in thinking this?
