I continue to be against factories. It's unnecessary, I'm still
convinced. Because it is the first option apparant to perform this task
does not mean it is the best. It also makes implementation very messy,
breaks all existing code in a /fundamental way/, causes many of the JDOM
newbies to be totally lost, and AFAIK still doesn't add significant
functionality.

We went through this once every month or so, so I'd refer you to the
archives for more details... I'm so far from being convinced this is
even a good idea, though...
