well, you *can* override them explicitly:

  module Bar
    def self.included(base)
      methods_to_override = %w[answer]
                          # or even <tt>instance_methods(false)</tt>

      methods_to_override.each { |method|
        base.send(:define_method, method, instance_method(method))
      }
    end
  end

if that's what you want... ;-)

cheers
jens
