Your functional interface provides for easy syntax. So please upload your take 2, so there's no need for Filter::Static at all :)
Update - or maybe the filtered one will still be easier to use. I'm now thinking of adding a counter so multiple statics can be defined on a single line, and I think the filtered version allows for more perlish syntax. Hmmm... what do you think?
Update2 - as far as I can see, the tied interface didn't change, which would mean I can upload the filter before you upload your new version - Or did I fail to see some obvious change?
