Bug 21904 – static range primitives should be usable directly

To iterate over a type that define the input range primitive, we must define an alias this: --- struct Conv { static StaticIterable b; alias b this; } struct StaticIterable { static Conv b; alias b this; // required // enhancement: could work without ? static void popFront() { } static bool empty() { return true; } static int front() { return 0; } } void main() { foreach (int i; StaticIterable){} //for (; !StaticIterable.empty(); StaticIterable.popFront()) // int i = StaticIterable.front(); }
