Naw, I was looking at "and the like": you import URI::Escape.

I will admit that your code would be a good place to go hunting to help in another implementation, and the import of URI::Escape highlights some of the issues you need to think about in addressing HTTP negotiations. It wouldn't be that hard to steal the appropriate stuff from that module, I suppose.

Oh: when I downloaded your .tar.gz, it was just a .tar -- either my browser did a conversion on the fly without changing the extension or you never gzipped your archive.
