        # This method sets the Double to have a stub strategy. A stub strategy
        # sets the default state of the Double to expect the method call
        # with any arguments any number of times. The Double's
        # expectations can be changed.
        #
        # This method can be chained with proxy.

        # When passed the subject, a DoubleDefinitionCreateBlankSlate is returned. Passing
        # a method with arguments to the proxy will set up expectations that
        # the a call to the subject's method with the arguments will happen,
        # and return the prescribed value.
        #   stub(subject).method_name_1 {return_value_1}

        # a stub Double with the method already set.
