  • So I'm not the only one who thinks Haskell is driven by arcane spells and sacrificed virgins :-P

  • This looks like a great tool for learning haskell. Definitely gives some insight into how that magical wizard that is haskell does that mystical lazy evaluation thingy.  Awesome!

  • @SealedSun: ...but casting arcane spells and sacrificing virgins is so much more fun than your mere conventional programming :)

  • @snmcdonald I was unable to get System.Vacuum.Cario/OpenGL/Ubi­graph to work. However, you can use GHood which is almost as easy. `import Debug.Observe; main = printO $ observe "sample list" [1..2]` This will launch a Java Applet that allows you to visually step through your code.

  • *** Exception: connect: does not exist (Connection refused)

  • Haskell - Sufficiently alien applied mathematics are indistinguishable from magic.

  • thats is really badass. emacs support plz
