Chains

It can be awkward at time to execute a series of operations.

simpleActor(Prnt(1)) {
  rsp1 => {
    simpleActor(Prnt(2)) {
      rsp2 => {
        simpleActor(Prnt(3)) {
          rsp3 => {
            simpleActor(Prnt("scadoo!"))(rf)
          }
        }
      }
    }
  }
}

Instead, we can simply create a list of operations and have them run by an actor.

val chain = new Chain
chain.add(simpleActor, Prnt(1))
chain.add(simpleActor, Prnt(2))
chain.add(simpleActor, Prnt(3))
chain.add(simpleActor, Prnt("scadoo!"))
Future(simpleActor, chain)
