You're right, the manual is broken in this respect. Right now, you
can't set the event mask in a CLEAR event handler. One way you could
do what you want is using defadvice -- add an after-advice to (clear)
that calls (watch whatever).
(defadvice after clear (watch all))
Jess may be changed again so that the code in the manual will cause
event-handlers to be reregistered; many things have been reorganized i
the last two releases and many more changes are coming.

Thanks. Sorry, my mistake; I have the test for this function commented
out in the Jess test suite. It will be fixed in a future version.

No, there isn't. I will include a way in a future version.
