Arrows and Signal Functions

Presenter: Dolan Paul

I was thinking of giving a talk that focused on arrows in a bit more detail. I'd like to use the concept of a signal function (very similar to the wires Handré was discussing at his FRP talk on 14-Oct-2013). I'd like to show how the signal function is implemented as an arrow, and how the arrow composition operators are defined. I found that this helped me understand more clearly how the state evolves as the signal functions are stepped. This will mostly be based on the publications from The Yale Haskell Group http://haskell.cs.yale.edu/publications/publications-chronologically/
