I have no idea. Programming is not my main area and thus I look for advice from other people to avoid doing stupid mistakes by following best practices. That being said, OO people will often point me to the design patterns book, etc. Is something similar needed for FP?

I've got the Haskell Craft book but haven't practiced enough. It seems good enough for me but, as people are learning more and more about using OO and FP in the real world (thus such criticism), I would like to keep current.
