The Manchester Lambda Lounge's next talk will see Ian Murray putting the func in Functors, by introducing us to Applicative Functors as they are used in Haskell.
Applicative functors are an abstraction that sit between functors and monads: weaker (hence more widely occurring) than monads, and stronger than functors. This practical talk will be split into two parts: 1. An introduction to the definition of the Applicative type class. Will show some examples of Applicative instances to get a feel for it. And then discuss how it's used; and how it achieves what a Functor can't. 2. Will look at the applicative-style of programming in Haskell, using user input validation as an example of this (including a brief detour to introduce the Monoid type class). -- Rick Moynihan http://twitter.com/RickMoynihan http://delicious.com/InkyHarmonics http://sourcesmouth.co.uk/ -- You received this message because you are subscribed to the Google Groups "NWRUG" group.
