<p>I have this book and use it all the time. Your five star rating is right on the mark.</p>
<p>I only have one bone to pick. There is an error that is repeated in example code throughout the book. The sacred-to-[sort] package globals<tt> $a </tt> and <tt> $b </tt>are used as generic temporary lexicals. That's harmless in the examples, but it's bad practice, and it might lead to grief for a reader experimenting with the code.</p>
