Everything Your Professor Failed to Tell You About Functional Programming I've been trying to learn Haskell lately, and the hardest thing seems to be learning about monads. "Monads in Ruby" and "Monads for Functional Programming" helped me finally to break the ice, but more importantly, they gave me a glimpse behind the veil.
