on CSS and the STYLE tag (emphasis mine):

type = content-type [CI]
This attribute specifies the style sheet language of the element's contents and overrides the default style sheet language. The style sheet language is specified as a content type (e.g., "text/css"). Authors must supply a value for this attribute; there is no default value for this attribute.

Regardless of my earlier comments to coming soon... I think this is tre' sexy. Heck, I even used a faux french word about it. Sure it is evil but it is the really fascinating kind of evil. Just don't name it Lingua::RPN::Perligata because that would be almost as hard to remember as Lingua::Romana::Perligata. Though your effort is at least recognizably perlish.

Actually, putting together the other post that just amused me, B::Deparse question with this one, I think you should write a B::Deparse::RPN so that we can insta-convert code to your new variant. =)

When I get votes, you get a big ole ++!
