I agree whole heartily with Jo Totland's September 29, 2002 review, and would add the following.If you can stay in the book every day, consistently, until you get through the book, it's not too bad (although, the flow is lacking). However, if you get four or five chapters into the book, put it down for a week and try to come back to it, forget it.It has also not been a very good reference for me.If you're working with PERL full time, you should probably have it. If you use PERL occasionally, you might want to borrow it first to see if it fits your style.
