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:<br><br><a href="http://en.wikibooks.org/wiki/Haskell">http://en.wikibooks.org/wiki/Haskell</a><br>
<br>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.<br>
<br>Also if you find yourself getting discouraged, I really like Brent Yorgey's article on the monad tutorial fallacy: <a href="http://byorgey.wordpress.com/2009/01/12/abstraction-intuition-and-the-monad-tutorial-fallacy/">http://byorgey.wordpress.com/2009/01/12/abstraction-intuition-and-the-monad-tutorial-fallacy/</a><br>
<br>It uses monads as an example but describes the process of learning difficult concepts.<br><br><div class="gmail_quote">On Sat, Oct 6, 2012 at 12:54 PM, Janek S. <span dir="ltr"><<a href="mailto:fremenzone@poczta.onet.pl" target="_blank">fremenzone@poczta.onet.pl</a>></span> wrote:<br>

</div>Good to hear, it's in front of me on the desk and I'm planning to finish that pearl tomorrow (BTW.<br>
Ross Paterson is the second author).<br>

</div>Yes, I know about the upcomming book and I'm awaiting it. Right now I'm digging through REPA<br>
papers, but Marlow's tutorial is next on my list of things to read.<br>

</div>Well, I figured out that before I go into more academic stuff I should have more knowledge about<br>
the basics, which I thought would be covered by RWH. Hence my frustration from not understanding<br>
a book that's supposed to introduce people to Haskell.<br>
<br>
I guess I'll start with reading some papers on parallelism and go back to RWH when I have more<br>
experience.<br>
