So that could be done like this.

<code>
# caveat : untested code
class Checkout

  def overall_instance_method
    "overall total on instance"
  end

  def class.overall_class_method
    "overall total on class"
  end

end

class Shopping

  def order
    # prepare order

    # with a Checkout instance
    checkout = Checkout.new
    puts checkout.overall_instance_method

    # with class method on Checkout
    puts Checkout.overall_class_method
  end

end
</code>

HTH,

Peter
