Cons
Con Poorly organized and hard to follow
The book jumps around, includes confusing function names and many of the code examples don't compile.
Con Not really "real world"
The book doesn't feel very "pragmatic". The title implies a practical approach to Haskell, but it takes way too long to be able to actually create something using this book as lot of time is spent on theory.
