I'm glad! I was a bit worried it was a lot of code all at once, but Monads are best grasped by lots of examples that flex the API instead of talking about them in the abstract. Feel free to email me if you have further questions.

(And I'm halfway tempted to write my own "Oi, fine, here's what a monad is" post soon enough. They're really not that strange, but it's easy to get things confused.)
