Hello, so, I'm having a simple problem with monads: I have no idea how to actually use them. I understand the category theory (or, at least well enough to be able to explain "what is a monad"); I understand the way to declare something as a monad instance, but I just don't get how to program with them. Can anyone provide me with, or direct me towards, some simple monads and some ways of using (for example) the monadic properties of lists? Thanks, Cory
