Yup, I too picked up that good habit in Perl, and thoroughly enjoy
being lazy with it. That said, I am doing development right now and
testing in both Safari 4.x and Firefox 3.5x, and the trailing comma
seems to work fine. I don't have access to any version of IE (well,
not easily anyway) so I haven't really tested.

Can someone please confirm the browsers/versions in which the trailing
comma croaks?
