- - Manual thread/lock -handling can be avoided

- - Testing the wrong async event order is easy. 
- - Also, testing long-duration workflows is easy as you can "fake" time passing

 It's always good to have alternatives, and if R3 is your alternative to Rx, then `FSharp.Control.R3` is your F# wrapper, like `FSharp.Control.Reactive` F#.
