Catching no generic method in EIEIO

Using EIEIO I can define a `slot-missing' method to catch "No Such Slot"
errors for objects which do not have this slot.

I've looked but as far as I can see, there is no ability to catch a
missing implementation for a method.


(defclass One()())

(defclass Two()())

(defmethod met((o One))

(met (One))
(met (Two))

The last form crashes -- I could, of course, implement this using
defmethod on Two, but I want to this for any method.
