Generic setf in defun-in-flavor

[p2@Porter.ASL.dialnet.symbolics.com (Peter Paine)]

Why can I not do:

    (defun-in-flavor ((setf func) flav) (value)
       ... )

I appreciate that defun-in-flavor can only handle specs of the form
(name-symbol flavor-symbol), not (spec-list flavor-symbol). But it seems
logical when using a defun-in-flavor to keep functionality exclusive to
the internal environment of a flavor, that CL principles of setfing the
accessor should be continued.

PS. Is there going to be any Zmail available about all the fabulous
things we cannot afford to fly to Stanford to hear in person?
