Example with snake is not compileable

[Sorokin-Anton]

https://github.com/Simre1/yampa-sdl2/blob/master/examples/Snake/Main.hs ends with

foodSF' :: SF (Player, Food) (Food, Food)
foodSF' = proc (p,f) -> do
  let ()

so its impossible to even compile it

Sorry, I do not think I will maintain yampa-sdl2 any longer. If you are interested, I have been working on a similar library (reactimate-game). This does not use Yampa but is heavily inspired by it.
