This provides good insight into some of the techniques used to make intuitively slow dynamic operations very fast in practice!

Good paper, but I wonder how relevant these optimizations are now that modern processors include indirect branch predictors.

Sounds similar to http://psyco.sourceforge.net/

It'd be nice to have a [pdf] warning in the title of this one.

I don't think I can edit it now. I'd guess it's because it's not a direct link, so it bypassed the pdf logic. Apologies.

Perhaps the submission page could have a PDF checkbox with the default state taken from the PDF autodetection function? This way we could correct the autodetection when it fails. Also it would ensure a uniform title "tagging" style.

Now that I think about it we could have radio buttons: Regular, PDF, Movie, Picture.
