Isn't `unreachable` in Zig like in C? So very bad things can happen if you overflow.

This sort of code makes me nervous about Zig.

In safe build modes (ReleaseSafe or Debug) it's an immediate panic, equivalent to calling `.unwrap()` on a None in Rust. In unsafe build modes it's undefined behavior.

Well exactly.
