Looks like latest urweb can't compile channel2.ur anymore. It says

dev:[grwlf at greyblade:~/proj/urweb/tests]$ urweb -dbms sqlite channel2
:0:0: (to 0:0) Function Channel2/monitor needed for both a link and a form
Make sure that the signature of the containing module hides any form handlers.
:0:0: (to 0:0) Function Channel2/put needed for both a link and a form
Make sure that the signature of the containing module hides any form handlers.

Channel2.ur doesn't use any forms so it is probably a regression, is it?
