I was thinking of the
(condition-case nil
(foo)
(error))
case... (I.e., with a missing handler body.) I'm not sure whether
that's supposed to or not. A handler is defined as
(CONDITIONS BODY...)
but a BODY in many other circumstances are allowed to be missing.
Also note that
(condition-case nil
(foo))
doesn't give a warning.
