Commits are quite old and pos-only syntax was not available 9 and 11 years ago: \r\n- https://github.com/python/cpython/commit/3f73ca23cfe4e4058689bc5a46622c68ef1b6aa6\r\n- https://github.com/python/cpython/commit/7c7cbfc00fc8d655fc267ff57f8084357858b1db\r\n\r\nSo, I propose to simplify these tests and make them more correct by using explicit pos only parameters. \r\n\r\nPlus, we can keep one test like this to be sure that chaning a parameter kind still works as before. But, there's no need in keeping these old tests the way they are.\r\n\r\nI will send a PR with the fix 👍 \n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-103407\n* gh-103536\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/sobolevn","@type":"Person","name":"sobolevn"},"datePublished":"2023-04-10T08:14:08.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/103406/cpython/issues/103406"}
