null lambda-list

[Steve Messick <messick%csvax.aberdeen.ac.uk@Cs.Ucl.AC.UK>]

May a generic function have a null lambda-list?  OK, I can't see much
use for it, but is it legal?  In pcl (system date 5/22/87 (rev 3)) the
following form dies:

	(defmethod foo ())

Furthermore, both following forms appear to construct methods which
require 1 parameter:

	(defmethod foo () (b))
	(defmethod foo (b))

The () might be considered a method qualifier except method qualifiers
are required to be non-nil atoms.
