But but but...

Suppose you have two classes <boat> and <plane> with their method (move).
And you want to do a class <hydroplane> and you wonder how to write the
method move for that class.

It you be nice to do something like

(defclass <hydroplane> (<boat> <plane>) ...)

(defmethod move ((self <hydroplane>) ...)
        ...
    (if condition (call-specified-method 'move '<boat>)
                  (call-specified-method 'move '<plane>)

        ...)


Anyway it seems to me that it would be nice, no ?
