I've been diving into aarch64 assembly recently building a small Forth. It's honestly really refreshing. If you're prepared to forgo some portability and pick an architecture assembly opens up a lot if options. Things like coroutines, automatic SIMD become easier to implement. It's also got amazing zero cost C FFI (and I'm only half joking). Linux kernel booting into a minimal STC Forth is a lot of fun. Not to mention you can run your code on android without SDK or NDK over ADB (in the case of aarch64).
