Abstract :
This position paper discusses the role of object identity in object-oriented systems. A distinction is drawn between object identity and object identifiers; the former is an intrinsic part of an object-oriented system, while the latter is not. An equality test on object identifiers breaches encapsulation; such a test should therefore only be enabled at the specific request of the implementor of an abstraction
