You mean the functions with names like fooM and fooM_? You can understand them better possibly by reading their source code, or when you write a do-expression, you could think if that can be expressed with a relevant fooM-function.

You could also take a look at this question.

I wrote a case study called "Anatomy of a New Monad". Is this what you meant?

The answer I was looking for is: [A tour of the Haskell monad functions][1]

But I'm still looking for something similar for the non standard monads.

The new O'Reilly book Real World Haskell has some good chapters on monads, which include the kind of ~~wacky ad hoc user-defined~~ abstract monad function stuff you seem to be looking for.
