Translate the Haskell into English Manually, Part II

This is part two of a two-part series [see linuxjournal.com/article/9096 for part one]. In this article, I build upon the concept of a parse pipeline with the State monad. Then, with all the pieces in place, I show the complete Haskell program. I also take a step back and consider why Haskell isn't as popular as some other languages and whether it deserves a place in your programmer's toolbox.
