Scala Async introduces async/await as the way of "simplifying" future and promise construction. I haven't played with this much as yet, I have generally just used Future in Scala.
Akka had something that was an extension of Scala's Future, but this is now deprecated in favour of Async. (The Akka stuff was way over-complicated to install and use.) Akka used to call this dataflow, and in the sense of dataflow as a single batch job making use of futures and promises to calculate a value, this could be seen as true. Dataflow though is about processes communicating with channels, and is far more interesting than what was called dataflow in Akka. GPars has this much more properly organized and spelled out (*). Go has gone the CSP, with elements of π-calculus, route and so can do dataflow but there are subtle issues which means dataflow should be different from π-calculus, and different from actors. This means D really needs a dataflow module to add to its data parallel module (std.parallelism) and actors module (std.concurrency provides what can be used as actors).
