how to find the last decorator of a chain

Hi,

I have something like this:

@render(format="a")
@render(format="b")
@....
def view(format, data):
  return data

Each render will do something with 'data' if format match, and nothing
if not.

But if there is no more renders to eval, the last one is the default,
and must run even if the format doesn't match.

In my understanding this equivalent to:

render('a',
 render('b',
  view(***)))

Is there any way to know, in this case, that 'a' is the 'default' format?

PS: the number of renders could be 1 or more.

Kind regards.
