   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. How do you do this is CLOS?

It's not a generic function doing it, but the designers of CLOS provided
slot-value for occasions like this.

(setf (slot-value self (slot-to-change button)) value)
