Methods for update-instance-for-different-class may be
defined to specify actions to be taken when an instance is updated. If
only :after methods for
update-instance-for-different-class are defined, they will
be run after the system-supplied primary method for initialization and
will not interfere with the default behavior of
update-instance-for-different-class. Because no
initialization arguments are passed to
update-instance-for-different-class when it is called by
change-class, the :initform forms for slots
that are filled by :before methods for
update-instance-for-different-class will not be evaluated
by shared-initialize.
Methods for shared-initialize may be defined to
customize class redefinition (see section 28.1.9.5).
