I'll re-submit it as multiple PRs; this is going to be a large change.\r\n\r\nFor this particular module, it could make sense to add a module state pointer to each type context, for easy and cheap state access.\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-101302\n* gh-101303\n* gh-101304\n* gh-101305\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/erlend-aasland","@type":"Person","name":"erlend-aasland"},"datePublished":"2023-01-24T08:08:49.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/101277/cpython/issues/101277"}
