Adding docstrings to namedtuples?

In Python 3, no wrapper is needed, as the __doc__ attributes of types is writable.

from collections import namedtuple

Point = namedtuple('Point', 'x y')
Point.__doc__ = '''\
A 2-dimensional coordinate

x - the abscissa
y - the ordinate'''

This closely corresponds to a standard class definition, where the docstring follows the header.

class Point():
    '''A 2-dimensional coordinate

    x - the abscissa
    y - the ordinate'''
    <class code>

This does not work in Python 2.

AttributeError: attribute '__doc__' of 'type' objects is not writable.
