Isn't it actually _PySequence_Fast_ITEMS (private API because of the leading
underscore)?  Here's one diff chunk from listobject.c:

    ***************
    *** 692,701 ****

            /* populate the end of self with b's items */
    !   if (PyList_Check(b)) 
    !           src = ((PyListObject *)b)->ob_item;
    !   else {
    !           assert (PyTuple_Check(b));
    !           src = ((PyTupleObject *)b)->ob_item;
    !   }
            dest = self->ob_item + selflen;
            for (i = 0; i < blen; i++) {
