--------------------------------------------------------
Some Objective-C classes allow a subclass to override a particular method in a
-parent class but expect that the overriding method also calls the overridden
-method in the parent class. For these cases, we provide an attribute to
-designate that a method requires a "call to ``super``" in the overriding
-method in the subclass.

This looks like an unrelated change.
