Applicatives are less "powerful" than Monads but considerably more common ... if you know what to look for. This talk will discuss Applicative Functors in Haskell paying particular attention to how they interact with effectual computation. The basis of the talk is taken from the paper: Applicative Programming with Effects by McBride and Paterson (soi.city.ac.uk/~ross/papers/Applicative.html). The talk will introduce the Functor and Applicative type classes in Haskell and provide some concrete examples of their use.
