Even at a higher level of abstraction, the compiler seems to pull through: https://godbolt.org/z/1nvE34YTe

It emits a cmp/jmp still when arithmetic would be fine though which is the difference highlighted in the article and examples in this thread. It's nice that it simplifies down to assembly, but the assembly is somewhat questionable (especially that xor eax eax branch target on the other side).
