Real World Haskell by Bryan O’Sullivan, Don Stewart and John Goerzen is an old book (2008) that approach teaching Haskell by building small programs. Sadly the language and libraries have changed enough to make several of the examples useless so I am making them working again. After I finish I pretend to make the changes listed as enhancements in the issue tracker.
