Hello,

I have an asynchronous control-flow like the following:

ActorA ! DoA(dataA, callback1, callbackOnErrorA)

def callback1() = {
  ...
  ActorB ! DoB(dataB, callback2, callbackOnErrorB)
}

def callback2() = {
  ActorC ! DoC(dataC, callback3, callbackOnErrorC)
} 

...

How would I divide this flow into several parts (continuations) and sequentially dispatch these to different actors (or threads/tasks) while maintaining the overall state?

Any hint appreciated, Thanks
