This I'm looking forward to :-)

For people who haven't seen, the PLT paper is "Programming the Web
with High-Level Programming Languages", http://readscheme.org/xml-web/

Their main trick is to make sending a HTML form to the user and
receiving the POSTed reply look, from the server program's point of
view, just like making a function call. The function can even return
multiple times, corresponding to the user going BACK to a previous
form and resubmitting it. Super clever! Like the difference between
Erlang processes and event-loop programming, but applied to the web.

Not that I've actually tried it :-)

They do this in Scheme using call/cc. Looking forward to seeing how
the mdisp-based approach works!

Cheers,
Luke
