A tail-call interpreter in (nightly) Rust

The user implemented a tail-call interpreter in Rust using the become keyword, achieving a 40-50% speedup on ARM64 and 2x speedup on x86-64 compared to their previous Rust implementation and hand-coded ARM64 assembly. However, the interpreter still lags behind the assembly backend, and its performance on WebAssembly is significantly worse, with a 1.2-4.6x slowdown compared to native performance.

Shared mutable state in Rust (2022)

To share a mutable value in Rust, you can use a combination of Arc and Mutex to ensure thread safety, but be careful not to lock the mutex in async code to avoid deadlocks. Instead, define non-async methods on a wrapper struct and lock the mutex there, or use an asynchronous lock if necessary, and consider alternative approaches like RwLock, arc-swap, or eventually consistent maps.
