It's explicitly not explaining what a monad is, first paragraph of the article: I've been informed that I didn't clearly explain what monads are and what the code examples are supposed to do. Sorry. I guess I assumed too much preexposure to monads. If you're no familiar with them, there are already so many tutorials on monads that I'll simply direct you to two of my favorites: spacesuits and wikipedia. I've also added more explanations of what the code snippets are supposed to do. I hope that helps. (The spacesuits link is dead (live[1]) and neither directly address "your motivating example" point, although the non-monadic vs monadic code comparisons demonstrate that monadic code can be much much shorter and less repetitive.)
