I think this is a bug and it should be fixed in 3.6. Currenly lru_cache breaks PEP 468 (Preserving Keyword Argument Order).

>>> from functools import lru_cache
>>> @lru_cache()
... def f(**kwargs):
...     return list(kwargs.items())
>>> f(a=1, b=2)
[('a', 1), ('b', 2)]
>>> f(b=2, a=1)
[('a', 1), ('b', 2)]

C implementation should be changed too.
