For that case, move all configurations to the several classes and configure
these flags in the concrete constructors. Interface will be more simple:
interface Sortable {
const ASC = 1;
const DESC = 2;
public function sort($direction = self::ASC, callable $callback = null);
}
class KeySorter implements Sortable {}
