Details:


Looking at the implementation of NSKeyValueObserving.m
(lines 1816, 1846)
 
.. willChangeValueForKey: (NSString*)aKey
               withSetMutation: (NSKeyValueSetMutationKind)mutationKind
                  usingObjects:(NSSet*)objects

and   

... didChangeValueForKey: (NSString*)aKey
              withSetMutation: (NSKeyValueSetMutationKind)mutationKind
                 usingObjects: (NSSet*)objects

I notice that the NSSet* object parameter is not being used, but instead the
property 'aKey' is being requested each time.

Should this implementation not use the passed NSSet* of objects when deciding
on the delta to report to the observers?

I have code running on OSX Lion that appears to do this, and from the function
signatures I expect that's the intended behaviour.
