This is a checklist for *having the discussion*.\nPlease try to *not* hold the individual discussions in this issue.\n\n* [ ] Dict watching API\n* [ ] Functions from PEP-523 not specified in PEP-689 (`_PyEval_EvalFrameDefault` \u0026 co.) -- this is a can of worms tho\n* [ ] FrameStack API (#91371)\n* [ ] `_Py_HashDouble`, see https://github.com/python/cpython/issues/91744#issuecomment-1111105784\n* [ ] PyBytesObject.ob_shash sounds like a good candidate: see https://discuss.python.org/t/15108 (guess fields need a slightly different naming convention though. Sigh. That should have been in the PEP.)\n* [ ] non-opaque access to frame structs and any other key APIs needed to implement alternate eval loops with comparable performance to the default eval loop (unless \u0026 until we can figure out stable public APIs that can deliver equivalent performance) - see [Nick's reply](https://mail.python.org/archives/list/python-dev@python.org/message/CW543RWJU6EWAPTWCDDHEUS37UHSAU5I/)\n* [ ] C APIs that provide access to compiled code whether in AST or opcode form (the API itself may be stable, but the compiled code isn't) - see [Nick's reply](https://mail.python.org/archives/list/python-dev@python.org/message/CW543RWJU6EWAPTWCDDHEUS37UHSAU5I/)\n* [x] ~~`PyLong_FromByteArray`/`PyUnstable_LongToBase30Digits`: https://discuss.python.org/t/20045~~ [there's now `PyLong_{From,To}NativeBytes\n* [ ] Anything that starts with an underscore and is documented\n* [x] ~~Fast access to PyLong contents~~ [`PyLong_Export`]\n\nGot any more?\nI offer to move other API to the unstable tier myself, *if there's a good usage example* to base docs \u0026 regression tests on.\n\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-101102\n* gh-102350\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/encukou","@type":"Person","name":"encukou"},"datePublished":"2023-01-17T16:06:54.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/101101/cpython/issues/101101"}
