PBP is a very good book. It gets actually better at each read. One thing touched only on the surface is logging (at least in the sense that it does not advise much about existing logging modules)

one thing I liked pretty much (and that can be said for perlhacks too) is that in the first reading (along the diagonal) you can ignore the bits you find a bit boring and browse the index for your favourite sections (some smelled real good just by the title ;)

Inside-out OO is maybe rushed a bit. I mean the arguments are sound and I knew the technique (eh eh from here++ actually) but I felt a bit "pushed" to embrace it...after all there is a huge codebase where almost everybody has invented its own object system, so a bit more of a pacific coexistence (or survival) howto would have been good.

still I buy a lot of books (and 80% are o'reilly books, enough to be given a prize some day :)) and PBP has been (is) my best read in months -- I must confess that on my bedtable (yeah it did not leave it yet!) it is sitting next to Pierce's Types theory and Queinnec's Lisp in little bits (and looks all the sexier...).
