60# Summary of changes made to the Python 2.5 code below:
61# * swapped ``partial`` for ``curry`` to maintain backwards-compatibility
62# in Django.
63# * Wrapped the ``setattr`` call in ``update_wrapper`` with a try-except
64# block to make it compatible with Python 2.3, which doesn't allow
65# assigning to ``__name__``.
