Perl has more freedom than Java. Therefore, books like this are more useful at listing the problems which need solving than they are at suggesting solutions to them for Perl programmers.

I owe a debt of thanks to OO design instructors who taught me to spot and solve common problems in Java. But, I had to augment their advice with a good deal of thought about the proper Perl tools for solving those problems. The solutions are rarely similar in implementation detail to the ones I was taught. Dare I coin a new term (which started as a sort of Freudian typo) and call these the 'properl' solutions, probably not.

My take is that if you are "brushing up," then you probably already know everything that such a book would cover. I have not been impressed with the "Head First" series at all (not very Perlish in my opinion). If you want a great book on OO, check out the Gang of Four book. If you want to simply "brush up," you can find lots of resources for free on the Internet.
