Something similar that I've been using:

@as_namedtuple("a b c d e")
class MyTuple:
    """My namedtuple with extra stuff."""
    @property
    def something_special(self):
        """..."""
        return ...

Support for default values is also something I've added, but that's
relatively orthogonal to this discussion.
