switch(X) {
	case 1: stuff; break;
	case 2,5,7: case 10: .. case 17: case 24,32: stuff; break;
	case 3,6,8: case 18: .. case 23: stuff; break;
}

This compiles on the new dmd. Only one item is allowed on a case range,
but you can just use fall through behaviour to make it its own case right
after the list.
