Thanks Matt:

Good tutorial on super. Maybe someone could add a keyword section to ruby-doc.

This leads me to a couple more questions on super and MacRuby inheritance:

1) Does MacRuby distinguish between Objective C subclasses and other Ruby 
classes or are all classes treated the same?

2) Can my inheritance path be arbitrarily long before I inherit from NSObject 
or an NS subclass?

3) If I have an empty init, e.g.,

        def init; super; self; end

        Can I always delete  the empty init and get the same result through 
inheritance?
