Play20 Promise sequence function

code.scala

// What is a Promise sequence function ?
// A function which transform a List[Promise[A]] into a Promise[List[A]]

// First naive implementation. It's a synchronous implementation (blocking).
def sequencePromises[A](list: List[Promise[A]]): Promise[List[A]] = {
  Promise.pure(
    list.flatMap(e => e.value match {
      case Redeemed(value) => Some(value)
      case Thrown(e) =>  { Logger.debug("thrown "+e); None }
    })
  )
}

// non blocking implementation?
