Default argument value is mutable

[liketic]

Hi,

Just want to confirm, I noticed there are some methods in ServiceClient contain a mutable default argument, for instance: `def get(self, url=None, params={}): """Create a GET request object.

    :param str url: The request URL.
    :param dict params: Request URL parameters.
    """
    request = self._request(url, params)
    request.method = 'GET'
    return request`

And the default argument params is changed inself._request(url, params). Is that as design? I just think it's a little wired. Thanks!
