Could you _please_ quote the relevant definitions when answering? It
causes a lot of extra work if I have to go constantly to previous
parts of the thread to dig them out. I still don't see why you can't
just write
(defmacro xgp-casi2-safe-call-iter (func largs)
(and largs
`(condition-case nil
(funcall ,func ,@(car largs))
(error (xgp-casi2-safe-call-iter ,func ,(cdr largs))))))
Or, if you really insist on "apply",
(defmacro xgp-casi2-safe-call-iter (func largs)
(and largs
`(condition-case nil
(apply ,func (list ,@(car largs)))
(error (xgp-casi2-safe-call-iter ,func ,(cdr largs))))))
