Actually the append_feature + super trick is somewhat
outdated in 1.8.0  - use  #included instead.

module M
end

class << M
    module ClassMethods # this avoids name pollution
        def class_method1
           p "class_method"
        end
        def class_method2
           p "class_method2"

        if mod.is_a? Class
            mod.extend ClassMethods
        else
            # maybe raise an exception ?
            raise "bla ..."
        end
    end

class C
     include M
