Generic Function Object-Id (2 methods)
(
object-id < obj > )
Returns a value that uniquely identifies an object in memory or in
a backend store. The default implementation looks for an 'id' slot via
'slot-value'. If such slot is not present, signals an
error. Specialize this function for various back end stores and other
object identification schemes.
