rails--rails/actionpack/test/controller/new_base/middleware_test.rb
Collin Miller 96650f704a added block arguments to ActionController::Metal#use
Useful for cases such as warden, where a block configuration is taken.

    class SomeController < ApplicationController
      use RailsWarden::Manager do |manager|
        manager.default_strategies :facebook_oauth
        manager.failure_app = SomeController.action(:authorize)
      end
    end
