Thats right. I can say about th eother languages buit try this:

class Foo
   def store(o)
      p self  # who am I?
      o.dave=1
   end
end
class SubFoo < Foo
   def initialize
      @dave=2
   end
   def store
      super(self)
   end
   protected
   attr_accessor :dave
end
sf = SubFoo.new
sf.store
p sf
