class MyApplication(object):
    def __init__(self):
        pass # process startup code

    def __call__(self, environ):
        yield None # must be a generator
        pass # request code

    def __enter__(self):
        pass # request startup code

    def __exit(exc_type, exc_val, exc_tb):
        pass # request shutdown code -- regardless of exceptions

We could mandate context managers!  :D  (Which means you can still wrap 
a simple function in @contextmanager.)
