In this blog, I will post solutions to the exercises from Real World Haskell, the excellent book by Bryan O'Sullivan, John Goerzen, and Don Stewart (O'Reilly, 2008).
Each solution will only use technologies and concepts presented up to that point in the book. (Some excercises become trivial using stuff that wasn't taught yet, but that's missing the point.)
Solutions will be accompanied by explanations (where relevant). And of course, this being a blog, everybody is invited to join the discussion.
