Thank you for fixing them so quickly! I look forward to also adding a separate HPy interface in the future (needs a few more features in HPy :-))

Some absolutely great issue reporting by @wenzeljakob recently. He's been working on making nanobind work on PyPy and has reported small reproducers (that's often the hard part!) for all kinds of corner cases and missing features in our C-extension API emulation. Thank you!

Interesting discussion on the future of the CPython C API and stable ABI, on the CPython discourse: discuss.python.org/t/lets-ge… mentions HPy a bunch of times

Let's get rid of the stable ABI, but keep the limited API

The stable ABI is an obstacle to improving CPython. The limited API, and the API in general, is also a problem, but much harder to fix. Let’s keep the limited API, at least until we have a completely...
