Can a C++ member function declare an Objective-C selector as a friend
(and/or the other way around)?

Also, in Objective-C++, can you have a scoped typedef in an Objective-C
class (eg. NSArray::iterator)?

Is there a way to add a member operator function to an Objective-C
class?

I am only a mirage.

No, because Objective-C has no concept of "friend" and so this would be
meaningless. Any piece of code can already send any Objective-C selector
to any object.

No, because Objective-C classes are not namespaces the way C++ classes
are, even in ObjC++.

No, because Objective-C classes do not have member functions, even in
ObjC++.
