the goal is to rewrite haku completely, starting with the VM---because it was the most obvious point of improvement
the reason is because Rust is kinda too verbose for low level stuff like this. compare the line numbers between haku1 and haku2's VM and how verbose those lines are, and it's kind of an insane difference
it also feels like Zig's compilation model can work better for small wasm binary sizes
and of course, I also just wanted an excuse to try out Zig :3
the arity of unary and binary ops is guaranteed by the fact they're, well, unary and binary ops.
right now there's no way to call them with less or more arguments, so we may as well.
introduce a new, more ergonomic syntax for haku
not all features are implemented just yet. still missing:
- custom tags (non-True/False)
- color literals
- lists
