This book is a fun way to bend one's mind into new shapes. It's reasonably well organized for reading straight through, up to the point where I stopped.

I didn't stop because I don't want to read the rest. I stopped because I knew that if I continued to the end now I wouldn't get enough from the rest of the book. Too much other stuff demands my attention to give Haskell the attention it deserves right now, and while I was able to get up to section 7.5 (halfway through chapter 7) without any real problems the cognitive load was getting a little heavy for me when I don't have the leisure to sit down at a computer and play around with Haskell for an hour each day to help me absorb what I've been reading.

If you want to learn some interesting mathematical concepts, this book could actually serve to help you. Some people have difficulty learning "pure" math, but get along much better learning the exact same concepts via programming. This book is densely packed with that kind of thing. Give it a try.

I don't know when I'll get back to Haskell, but when I do I'm pretty sure I'll be happy to have this book near at hand. It's dry, but clear, interesting, and instructive. ( )
