[Haskell-cafe] Am I the only one having problems with RWH?

I found I had to keep switching between RWH and other books for these
concepts to sink in. A really good resource that I don't see mentioned too
often is the Haskell wikibook:


I don't remember it covering parsec specifically but if you get grounded in
all the concepts there, the RWH chapters on parsec will make more sense. It
also helped me to take breaks from RWH and re-read chapters later.

Also if you find yourself getting discouraged, I really like Brent Yorgey's
article on the monad tutorial fallacy:

It uses monads as an example but describes the process of learning
difficult concepts.
