Future instance

[mfirry]

Hi and thanks for this (and everything else you work on).

Coming back from Scala Days, I was experimenting a bit with this sort of things and came out with a silly instance for Future along these lines:

delegate for Monad[Future] {
  def (fa: Future[A]) map[A, B](f: A => Future[B]): Future[B] =
    fa.map(f)
}

My question is how would one go about passing the required ExecutionContext.

Thanks!

Hi. I was wondering if anybody had time to help me with this. Otherwise I'll close it, no problem.

implicit val ec = scala.concurrent.ExecutionContext.global

delegate for Monad[Future] {
  def (fa: Future[A]) map[A, B](f: A => Future[B]): Future[B] =
    fa.map(f)
}

Future is a monad, I truly recommend trying to to avoid using at a Monad as how its typically used, side-effecting is not.

So this is only useful when used in a way future is never actually used as.

Otherwise I think future would need here as well to rely on scala 2 mechanisms at the implicit context is not available.

Thanks so much Christopher!
