However, if the enum was created using multiple values, and the lookup call erroneously passes multiple values instead of one tuple with those multiple values, then the creation branch is chosen and the resulting error message is less than useful.\r\n\r\nWhich branch to take should be determined by whether the enum is final (has members).\r\n\r\n\u003c!-- gh-linked-prs --\u003e\r\n### Linked PRs\r\n- gh-99500\r\n\u003c!-- /gh-linked-prs --\u003e\r\n","author":{"url":"https://github.com/ethanfurman","@type":"Person","name":"ethanfurman"},"datePublished":"2022-05-10T22:48:22.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/92647/cpython/issues/92647"}
