Here's docs:
.. staticmethod:: factory(*keys)
Return a callable object that creates a dictionary from *keys* and its
operands. For example:
* ``dict.factory('1', 2, (3,))({1}, [2], {3: None})`` returns
``{'1': {1}, 2: [2], (3,): {3: None}}``.
* ``dict.factory((3,), '1', 2)({1}, [2], {3: None})`` returns
``{(3,): {1}, '1': [2], 2: {3: None}}``.
Equivalent to::
def factory(*keys):
def f(*values):
return dict(zip(keys, values))
return f
Hope it makes my idea clearer.

> I think you've got it backwards -- if you send the patch the idea *may* be
> accepted. You ought to at least show us the docs for your proposed factory,
> it's a little murky from your example.
