Welcome to a new way to learn Haskell. Perhaps you are coming to this book frustrated by previous attempts to learn Haskell. Perhaps you have only the faintest notion of what Haskell is. Perhaps you are coming here because you are not convinced that anything will ever be better than Common Lisp/Scala/Ruby/whatever language you love, and you want to argue with us. Perhaps you were just looking for the 18 billionth (n.b.: this number may be inaccurate) monad tutorial, certain that this time around you will understand monads once and for all. Whatever your situation, welcome and read on! It is our goal here to make Haskell as clear, painless, and practical as we can, no matter what prior experiences you're bringing to the table.
