If you're implementing a subclass, you can, within your implementation, explicitly call the superclass's method, even if you've overridden that method, i.e.:
[self overriddenMethod]; //calls the subclass's method
[super overriddenMethod]; //calls the superclass's method
What if you want to call the superclass's method from somewhere outside the subclass's implementation, i.e.:
[[object super] overriddenMethod]; //crashes
Is this even possible? And by extension, is it possible to go up more than one level within the implementation, i.e.:
[[super super] overriddenMethod]; //will this work?
