In fact, some of the work runs parallel to it and will actually help it.\r\n\r\nThere are 3 wins I can observe right now:\r\n* deferring `LOAD_GLOBAL`\r\n* deferring `LOAD_ATTR`\r\n* deferring frames' strong references on the code object and function (this is the hardest of the three)\r\n\r\nI shall proceed in this order.\r\n\r\n### Has this already been discussed elsewhere?\r\n\r\nNo response given\r\n\r\n### Links to previous discussion of this feature:\r\n\r\n_No response_\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-123128\n* gh-124085\n* gh-124101\n* gh-124894\n* gh-125711\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/Fidget-Spinner","@type":"Person","name":"Fidget-Spinner"},"datePublished":"2024-07-07T15:10:27.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/121459/cpython/issues/121459"}
