Also, once https://github.com/python/cpython/issues/145854 and https://github.com/python/cpython/issues/145855 are implemented, it would make the bytecode for deletion more consistent. \n\n### Has this already been discussed elsewhere?\n\nThis is a minor feature, which does not need previous discussion elsewhere\n\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-146314\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/markshannon","@type":"Person","name":"markshannon"},"datePublished":"2026-03-12T11:48:35.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/145857/cpython/issues/145857"}
