Except that the programmer still writes >methods; all this generic function stuff is done internally. I thought they were the same too until someone at work came up with this problem in Flavors: (setf (send self (send button :slot-to-change)) value) What is happening is that (send button :slot-to-change) returns the name of a slot to change and that slot is changed to VALUE on the object SELF.
