Welcome to issue 221 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of March 25 to 31, 2012.

Quotes of the Week

   * Tekmo: Now I have a monoid in the category of problems.

   * hpc: atomically the whole thing

   * BMeph (in "announcer voice"): In a world, where orphan instances
           collide, one language holds the key to successful compilation, in
           our time.

   * thoughtpolice: if there is a question, edwardk probably has the
                    answer

   * danharaj: All I have to do is remove me from the program and it
               works.

   * anonymous: Caveat implementor.

   * ski: 'getLine :: IO String' is a recipe for how to interact with
          the world to acquire a `String'
     ski: the recipe is not the cake
