Users of PySequence_GET_FAST() should get the length of the sequence using

PySequence_Size(), not PyObject_Size(): the later considers the mapping
methods as well as the sequence methods, which is not needed here.  Either
should be equally fast in this case, but PySequence_Size() offers a better
conceptual match.
