Yeah I've been writing a lot of Rust for my compiler and it's so much fun. But it still bugs me that indexing panics. Returning an Option would make a lot more sense... What I've been wondering for my own language is whether I could design something like Rust's borrow checker but for ranges of values. That way I can guarantee valid indexing.
