In ast.c, set_context checks for assignment to an empty tuple, but not an empty list.

        case List_kind:
            e->v.List.ctx = ctx;
            s = e->v.List.elts;
            break;
        case Tuple_kind:
            if (asdl_seq_LEN(e->v.Tuple.elts))  {
                e->v.Tuple.ctx = ctx;
                s = e->v.Tuple.elts;
            }
            else {
                expr_name = "()";
            }
            break;
