One more thing: this is just a different spelling for what was previously already exposed as `__attribute__((assume))`; I’m not sure if/how familiar you are with that one, but I hope its semantics align with what `[[omp::assume]]` is supposed to do. I’m asking because I’m not terribly familiar with OpenMP myself.
