# foo,
)get_patched_ast will incorrectly scan past the empty tuple and cause MismatchedTokenError.
The following test case will blow up in _consume_pattern because it does not match the pattern
def test_empty_tuple_node4(self):
source = "a = (\n# foo,\n)"
ast_frag = patchedast.get_patched_ast(source, True)
checker = _ResultChecker(self, ast_frag)
checker.check_children("Tuple", ["()"])
