            functions are applied so that the call order is the same as the

    Like decorator_from_middleware, but returns a function
    that accepts the arguments to be passed to the middleware_class.
    Use like::

         cache_page = decorator_from_middleware_with_args(CacheMiddleware)
         # ...

         @cache_page(3600)

    Given a middleware class (not an instance), returns a view decorator. This
    lets you use middleware functionality on a per-view basis. The middleware
    is created with no params passed.
