The original proposal:
return app(request.envrion, self.start_response)
still works. It's returning the application instance itself that
doesn't work. Maybe it did in an earlier version, or maybe I'm
misremembering something similar from another context.
BTW, you can also get 'environ' and 'start_response' as magic action arguments:
def my_action(self, environ, start_response)
That's how I've been doing it, but I'm going to switch to forward().
