Discussion
During the evaluation of an NSWhose object that contains a test whose operator is NSEqual, an is message may be sent to each potentially specified object, if neither the potentially specified object nor the object being tested against implements a scripting method.
The default implementation for this method provided by NSObject returns true if an is message sent to the same object would return true.
