[Haskell-cafe] ANN: Silkworm game

I'm not too much of an expert in Haskell, but I did notice that  
building the game required keeping track of a lot of state  
information, which was not very intuitive in Haskell (although the  
OpenGL state info is rather intuitive).  If I were to do it in Haskell  
again, I would try to learn more about FRP (Functional Reactive  
Programming) and see if that improves things in terms of state.

Ruby is my favorite imperative language, so I would certainly  
recommend it for game development.  It would likely be much easier in  
Ruby, but perhaps a little slower.  My experience with Ruby on Rails  
has been that it is always a little slower than I wish it were :)
