For present stdlib functions and kinds like vector that aren't absolutely bounds-checked, the aim is for these features for being bounds-checked when called from code Using the bounds profile on, and unchecked when known as from legacy code, quite possibly employing contracts (concurrently getting proposed by various WG21 associates).
