I know nothing about Zig, but this is pretty interesting and looks well designed. Linus was recently very mad when someone suggested a new semantics for overflow:

—— I'm still entirely unconvinced.

The thing is, wrap-around is not only well-defined, it's common, and EXPECTED.

Example:

   static inline u32 __hash_32_generic(u32 val)
   {
        return val * GOLDEN_RATIO_32;
   }

and dammit, I absolutely DO NOT THINK we should annotate this as some kind of "special multiply". —-
