This can happen either because a subclass includes a slot specifier with the same name as a slot specified in a superclass or because multiple superclasses specify slots with the same name.
Multiple inheritance doesn't dramatically change any of the mechanisms of inheritance I've discussed so far--every user-defined class already has multiple superclasses since they all extend STANDARD-OBJECT, which extends T, and so have at least two superclasses.
Thus, methods specialized on different classes could end up manipulating the same slot when applied to a class that extends those classes. London firefighters battled a spectacular blaze in a farm field in the city’s southeast end after flames erupted from a tractor.
