This code (MCL 2.0.1):
(defclass m1 (standard-class) ())
(defmethod shared-initialize :around
((m m1) slot-names &rest initargs &key direct-superclasses)
(call-next-method m slot-names :direct-superclasses nil))
(defclass c1 () () (:metaclass m1))
jumps to this error:
> Error: Bad initarg: T to call-next-method for #<M1 #<Unbound>>
> on #<STANDARD-GENERIC-FUNCTION SHARED-INITIALIZE #x295E6E>
> While executing: CCL::CNM-WITH-ARGS-CHECK-INITARGS
> Type Command-. to abort.
See the RestartsI menu item for further choices.

Without changing the arguments of call-next-method, everything is allright:
(defclass m2 (standard-class) ())
(defmethod shared-initialize :around
((m m2) slot-names &rest initargs &key direct-superclasses)
(print "shared") (call-next-method))
(defclass c2 () () (:metaclass m2))
Is there allready a patch fixing that?
Thanks,
