Funny you should mention the Typeclassopedia. The guy who wrote the Typeclassopedia (Brent Yorgey) is coming to speak to my local functional languages group up on campus tomorrow. In the process of googling him, I came across both the Typeclassopedia and this article, and both were excellent. This tutorial was just one of the those "aha!" moments in my life, and I wanted to share.
