Maybe you could place Yampa in a Darcs depot? I will have some time now to study Yampa and apps again. To train myself, I would try to make a simple bouncing ball, then a Pong like game, and then I would like to convert the C++ minigames I made for my students. These might serve as simple tutorials for other people? After revision of course, because I'm a newbie, so you can expect some horrible Haskell code ;) Cheers, Peter -----Original Message----- From: Henrik Nilsson [mailto:nhn@Cs.Nott.AC.UK] Sent: Monday, December 17, 2007 5:05 PM To: paul.hudak@yale.edu Cc: Peter Verswyvelen; haskell-cafe@haskell.org Subject: Re: [Haskell-cafe] Yampa / AFRPVectorSpace.hs Hi Peter, Oops! Yes, as Paul says, clearly an error. My best guess is that it was commented out at some point for testing something, and then forgotten! The error does not occur in my local copy of the code, so a version skew problem to boot, I'm afraid.
