There's no checked arithmetic in Go, right? I guess the difference between Go and C/C++ is that Go at least won't optimize away the overflow check? But it still doesn't insert it for you either.

In Go, overflow is not checked, but it is well-defined in the spec including `programs may rely on "wrap around"`: https://go.dev/ref/spec#Integer_overflow
