You guys inspired me, so I wrote another Program Repair Shop and Red Flags article which went up on www.perl.com today. The article takes an old crufty piece of Perl 4 code and tries to improve it. Here's the description from the web site:

Once again I take a real program written by a genuine novice and show how to clean it up and make it better. This time we turn a perl4 library into a Perl 5 object-oriented module. I show how to recognize some "red flags" that are early warning signs that you might be doing some of the same things wrong in your own programs.

Enjoy.
