Useful Package Level Implicits for Option and ::
package object sandbox {
type ?[A] = Option[A]
// val a: ?[Int] = 1 Some(1): ?[Int]
implicit def instanceToOption[A](instance: A): ?[A] = Option(instance)
def Some[A](instance: A): ?[A] = Option(instance)
// val a: ?[List[Int]] = None None: ?[List[Int]]
// val b = a(_.sum) None: ?[Int]
