Rewrite the book to use Haskell instead of Scala

Go through all code examples and try to write them in Haskell instead of Scala. This will discover which code examples have no reasonable Haskell equivalent at the same pedagogical level as appropriate at each place in the text.
Go through all exercises and try to implement them in Haskell. See if there are any problems specific to the differences between Haskell and Scala.
Identity all text that specifically addresses features of Scala that do not have any counterparts in Haskell. See if that text can be removed without disturbing the flow of the presentation, or can be replaced by some Haskell-specific equivalent.
