Hi everyone, I've been writing a bunch of in-depth monad tutorials that I thought some of you might find useful. So far there are six, with at least three more planned. Here are the links: Part 1 (Basics): http://mvanier.livejournal.com/3917.html Part 2 (>>= and return): http://mvanier.livejournal.com/4305.html Part 3 (The monad laws): http://mvanier.livejournal.com/4586.html Part 4 (The Maybe and list monads): http://mvanier.livejournal.com/4647.html Part 5 (Error-handling monads, part 1): http://mvanier.livejournal.com/5103.html Part 6 (Error-handling monads, part 2): http://mvanier.livejournal.com/5343.html The next ones will deal with state monads. I would love to get some feedback on these. Cheers, Mike
