I skimmed this book over the weekend (thank you for the PDF download). There's an incredible amount of work in this book, and I appreciate that.
However, having said that, I suffer when I read this book in the same way I suffer when I read MJD's "Higher Order Programming". They both seem to require a bit more computer science background than I have (or have patience for). I'm a street-trained programmer, and have never set foot in a CS classroom.
In other words, my head hurt while reading this book, but that's not your fault. :)
