You could try this too (untested):

  class Class
    def autoinit(*args)
      # Define "initialize" in terms of the symbols contained in *args
    end
  end


  class Example
    autoinit :a, :b, :c
  end

Now, even though it's untested, I'm pretty sure it wouldn't work, cos
I left a hole for you to fill :)  (i.e. I started it and it became too
hard)
