One other technique that might be relevant is Module#included, which
as I understand it is essentially a new name for append_features.  (Is
that accurate?)  Here's a 1.8.0 example:

  module M
    def self.included(c)
      def c.something
        puts "I'm a class method!"
      end
    super
    end

    def another
      puts "I'm an instance method!"
    end
  end

The inclusion now operates, with fairly clear separation, on both the
class and the instances:

  class A; include M; end

  A.something
  A.new.another
