The bug is in the middle of page 157 in the version downloaded february 15.
BTW, thanks for a great book! I think it's very pedagogic. I haven't programmed in neither Scala nor Java at all before and I have very limited experience with functional programming, but so far (at page 157) I haven't had a single moment where I couldn't figure out how something works. I've had many "wow, cool!" moments though. I'm a professional UNIX admin and Ruby programmer and I know my way around C, C++, sh, Python, Awk and many other non-functional languages. I'm looking forward to continue reading the book and even more to actually start using Scala for something non-trivial (whatever it might be).
