I'm in the midst of writing my column for ;login: at the moment, and I was about to write up a piece on the Factory design pattern. Just for kicks, I checked do see if anything had been written about this. Turns out, Sean Hunter wrote something about it for TPJ #22. There's a lot of knowledge about design patterns in Perl that aren't being written down (yet), so I decided to find something else to try and write about instead.
If you want to read more about design patterns and Perl, I've started a resource list. Suggestions heartily welcome.
Oh, and Matt's new article on Proxy Objects is pretty cool, too. :-)
It would probably be useful to have a listing of modules implementing various patterns, like, say Class::Factory and Class::Observable, among others
Factory method, on Patterns in Perl.
It's basically a straight copy of the GoF chapter, and I'd be interested to include more perlish stuff if you come up with it. I'm sure the abstract superclasses can be better handled.
