I am sure of it but again I'm not really positive. I just know it's
one of those have toos.
Another place you're likely to see it and it keeps with subclass of
subclass is dealing with a document based app.
If you are using an NSWindowController then you are likely to have to
do something like
SomeDocumentClass * document;
document = (SomeDocumentClass*)[self document];
in the windowDidLoad method.
The exact and accurate information on all this though would have to
be offered by another person, since I don't fully understand it myself.

Interesting that the two times you used it was with a subclass because
the instance in this case is a subclass of an NSObject subclass.
SimpleTreeNode is a subclass of TreeNode, which is a custom subclass
of NSObject. This can all be seen in the DragNDropOutlineView
example. Maybe this syntax is specific to some type of inheritance or
custom class issues?
