Midgets with dildos

Description:Well, in this dumb example, you might want to implement a division operator. It's incumbent on the caller to check for whether it's an instance of Nothing or Just MyVal; there's no "null" in the picture. Why would Nothing be useful? I'm not a Haskell hipster and I personally think that people trying to advocate that language and FP in general do themselves a huge disservice by focusing so heavily on monads and other type calculus concepts in introductory contexts.
