This one puzzles me - I know there's something fundamental that I'm not
understanding about Ruby's object model. Consider these classes:

class Base
  def self.my_name=3D(value)
    @my_name =3D value
  end
  def self.my_name
    @my_name
  end
end

class Derived < Base; end

Base.my_name =3D 'John'
puts Base.my_name
John

Derived.my_name
nil
Derived.my_name =3D 'Mike'
puts Derived.my_name
Mike

So the class instance member @my_name isn't inherited by the Derived class.

How do I share state between a derived class and its base class?

Thanks
