The single quote strangeness was due to a copy/paste from GoogleDocs. I'll have to keep that in mind when using that to share code. The """ is starting to make more sense now. I'm not sure if I have any preferences for documentation style yet. I like POD for the space it gives the text, except when I don't want to look at it, especially since I tend to prefer keeping the documentation near the methods. Javadoc is easily hidden in Eclipse, but I'm a little put off by its differentness. I haven't seen a style that really grabs me so far.
I was in two minds in the printargs method. It looks better the way you've written it. I was trying to keep it simple so that people with no knowledge of Perl could see how it works, but I do like the for line. Likewise, I'd used lots of whitespace in the attribute distributions to make it 'friendlier'.
