And @action is a decorator that requires arguments. Using @action is only
needed if you need to tweak the default's, ie, to limit the calling to a
request_method, or to assign a renderer. If you're doing something like:
config.add_handler('home_page', '/', handler=Home, action='index')
Then you don't need to use @action if its going to return its own Response
object.
So the easy way to think of it, the methods in your handler are all actions
still (just like in a Pylons 1 controller!), *but*, if you need to modify how
the action is called, how the return value of it is handled (ie, using
renderer), or how the action is registered (ie, its name), then you use the
@action decorator to modify those parameters.

from pylons.controllers.util import Response
Then return a response object:
def login(self):
login = db.load_form('login.hh')
response = Response(login)
response.content_type = 'application/vnd.mozilla.xul+xml'
return response

Yup.
