The relation between names is not obvious, when you see `\u003cclass 'builtin_function_or_method'\u003e`, it is hard to defer that it is `types.BuiltinFunctionType`.\r\n\r\nAs result, these types cannot be pickled:\r\n```pycon\r\n\u003e\u003e\u003e pickle.dumps(types.ClassMethodDescriptorType)\r\nTraceback (most recent call last):\r\n  File \"\u003cstdin\u003e\", line 1, in \u003cmodule\u003e\r\n_pickle.PicklingError: Can't pickle \u003cclass 'classmethod_descriptor'\u003e: attribute lookup classmethod_descriptor on builtins failed\r\n```\r\n\r\nI propose to change attributes `__module__`, `__name__` and `__qualname__` of all builtin types exposed in the `types` modules so that they will match names under which they are accessible.\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-100130\n* gh-100142\n* gh-100405\n* gh-100406\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/serhiy-storchaka","@type":"Person","name":"serhiy-storchaka"},"datePublished":"2022-12-09T08:42:24.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":6},"url":"https://github.com/100129/cpython/issues/100129"}
