Yet one bug: PR 30888 only changed the text output. But there is also the html output generator.

I'm not sure - if I revert the change like this: if isinstance(getattr(obj, name, None), __future__._Feature): - return False + pass # return False then test_html_doc fails: ====================================================================== FAIL: test_html_doc (test.test_pydoc.PydocDocTest.test_html_doc) ---------------------------------------------------------------------- Traceback (most recent call last): File "/Users/iritkatriel/src/cpython/Lib/test/test_pydoc.py", line 414, in test_html_doc self.assertEqual(text_lines, expected_lines) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ AssertionError: Lists differ: ['tes[1392 chars]t]', "print_function = _Feature((2, 6, 0, 'alp[156 chars]ody'] != ['tes[1392 chars]t]', 'type_union1 = typing.Union[int, str]', '[72 chars]ody'] First differing element 55: "print_function = _Feature((2, 6, 0, 'alp[36 chars]576)" 'type_union1 = typing.Union[int, str]' First list contains 1 additional elements.
