I think it's a pretty good book. I've managed to get a bit more than half way through it. I must admit I haven't actually played with the code presented, but it certainly makes one think about how to write code such that you can use it later for something completely different from what you might be thinking about immediately. For that it I certainly ++ the book.

It also has a good description of how to undo recursion for performance gains.

Since getting about 1/3 the way through, I've not been able to figure out where it's going such that it might benefit me. Sure it's useful if you happen to have to deal with infinite or nearly infinite lists, but I don't, so I'm not sure if the rest of the book is going to ever benefit me. I'm hoping so, and all knowledge is a good thing, but I'm hoping to learn more that I can apply to my life in the near future. I could cheat and skim ahead, but I haven't yet...

So, if someone else might know about the lessons awaiting me toward the end of the book, I'm listening.

Oh, and as ghenry said, the errata is online, and the code is online, so mistakes in either version shouldn't make too much difference if you read the online info.
