I never really got into Haskell in a big way, but one of the things I liked about the Haskell Wikibook [1] was how they presented Haskell code as being either in pure form or "do" form, and how the latter orchestrates the former, much as presented here. To a beginner like me not interested in monads etc, this was a very simple and explicit way of approaching coding in Haskell.
