i've been setting up all my classes like this:


   class C

     class << self
       def init
         @foo = 4
         @bar = 2
       end
     end
     self.init


     attr :foo

     def initialize arg = nil
       @foo = arg || klass.foo
     end

     def klass
       self.class
     end

   end

same thing - bit more convenient.
