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?
