slot-value-using-class class object slot => value
Arguments and values:
class -- A class metaobject. It is the class of the object argument.
object -- An object.
slot -- An effective slot definition metaobject.
value -- An object.
This generic function implements the behavior of the slot-value function. It is called by slot-value with the class of object as its first argument and the pertinent effective slot definition metaobject as its third argument.
The generic function slot-value-using-class returns the value contained in the given slot of the given object. If the slot is unbound slot-unbound is called.
The results are undefined if the class argument is not the class of the object argument, or if the slot argument does not appear among the set of effective slots associated with the class argument.
