Hi alex, The only thing I can tell you is that I use Arrow a lot to map element of a tuple, and that is really neat (took me a while though to get the signature of the method and map to the instance defined).
Basically: f *** g = \(a, b) -> (f a, g a) Now that I got this one, I can see the more general abstraction and that looks extremely powerful. Hope that help!
