I think there is also some work done about using Arrows for this  
problem, cf John Hughes' original paper. (I hear the use of Arrows was  
inessential, see the followup by Thiemann.)

IMH-and-probably-offtopic-O, the continuation-based approach is  
semantically nice but I don't think anyone has reconciled it with the  
general desire for clean and tidy URIs. Going to:

http://example.com/continuations/45345345

is not anywhere near as aesthetic / phishing proof / ... as going to  
e.g.

http://example.com/comments/edit/16

(Though I grant that hpaste URIs are tantalisingly mysterious.)

The general problem is providing a way for the programmer to  
(schematically) specify the URIs and handlers without getting bogged  
down in state machine encodings.

If someone's got some good ideas here, I'd love to hear about it (on  
the web-devel mailing list, perhaps).

cheers
