Creative uses of monads

Question

I\'m looking for creative uses of monads to learn from. I\'ve read somewhere that monads have been used for example in AI, but being a monad newbie, I fail to see how.

Answer 1

Phil Wadler has written many papers on monads, but the one to read first is a lot of fun and will be accessible to any programmer; it's called The essence of functional programming. The paper includes source code and sample usages.

A personal favorite of mine is the probability monad; if you can find Sungwoo Park's PhD thesis, it has a number of interesting example codes from robotics.
