Subinterpreters are not the only reason to do this (and they're not *my* reason to do it). Adding a way to create PyStructSequence heap will help users of the stable ABI, where reduced performance is a known tradeoff (see https://www.python.org/dev/peps/pep-0652/#stable-abi: "The Stable ABI trades performance for its stability"). More generally, this would need solving one of the remaining limitations of the limited API (PEPs 489, 630): type-specific data. If Hai Shi solves the problem, the solution will be useful even if PyStructSequence_FromModuleAndDesc turns out useless. Using the proposed new API in CPython's stdlib should be done much more deliberately, and yes, would need a PEP. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45113> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
