Having each of the generic range functions return a <FN>Result type that all implement some variations of a random access range is absurd. Having "auto map(); Returns an input range" is much denser and helpful than "MapResult map(); struct MapResult { @property bool isEmpty(); ...}". A more explicit "impl(InputRange) map()" may be better until you consider that map is generic on the kind of range you give it, so that just turns into "impl(MapResult!R) map(R)()". A more roundabout, pointless way of saying "auto". |
