In the last installment in this series, we talked about separating the side effecting code from the pure functions. I gave examples in both Haskell and F# to accomplish this goal, although with Haskell it’s more intuitive due to encapsulating the side effects within the IO monad. This time, let’s cover how we can abstract the monadic code through the use of type classes. Using the book, Real World Haskell, has opened up a lot of possibilities in this area.
