I'm also a Haskell no-so-new-anymore-bie, and for me, understanding
monads was a question of first reading the available docs, especially
plus reading the Haskell School of Expression <http://haskell.org/soe/>
but mainly, creating some of the monad instances myself, step by step (I
started with a random number generator, and ended with the list monad).
I found this very useful, and I actually had to look many times to the
existing solution to get it right. It made me appreciate the genius
minds behind this. After a bit of practice, I can now use monads almost
as easy as I can write imperative C/C++/C# code, although I find this is
also the dangerous part of the do notation: you tend to forget the
beautiful pure functional implementation that is behind the scenes, and
start to think imperatively (again)...
If you want I can dig up my old source code where I converted a random
number generator from a purely functional approach to a monadic
approach, but I'm not sure reading it would help you, it's creating the
code yourself that will be useful I guess.
