Functional reactive programming is a highly declarative way to write event driven systems. No more observer pattern! No more bugs. Functional reactive programming is a paradigm shift, it revolutionizes the way people write event driven code. Sodium FRP library and the coming FRP book by Manning will start this revolution on a wide scale. This group is meant for people who don't want to suffer anymore from the six plagues of the observer pattern and want to be among the pioneers who embrace this simple but powerful shift in thinking.

Please let me know if you would like to give a presentation about this paper.
Functional Reactive Programming (FRP) extends a host programming language with a notion of time flow. Arrowized FRP (AFRP) is a version of FRP embedded in Haskell based on the arrow combinators. AFRP is a powerful synchronous dataflow programming language with hybrid modeling capabilities, combining advanced synchronous dataflow features with the higher-order lazy functional abstractions of Haskell. In this paper, we describe the AFRP programming style and our Haskell-based implementation. Of particular interest are the AFRP combinators that support dynamic collections and continuation-based switching. We show how these combinators can be used to express systems with an evolving structure that are difficult to model in more traditional dataflow languages.
