? (let (a b) (setf (values (values a b)) (values 1 2)) (list a b))
(1 2)
? 

Should return (1 nil), by my reading of ​http://www.lispworks.com/documentation/HyperSpec/Body/05_abc.htm.

The spec says a program-error is required for unsupported options. This may have been augmented by the MOP, I don't know. But in any case, some indication of a problem should be given at some point.

After a little poking about, it seems like the problem is this method:

 (defmethod initialize-instance :before ((class class) &key &allow-other-keys)
  (setf (%class.ctype class) (make-class-ctype class)))

The &allow-other-keys in this method causes keyword arg checking for class objects to be disabled. I wonder it it would be worthwhile (or even allowed) to treat methods that have &allow-other-keys without &rest as not disabling initialization arg checking.
