Posting for the whole Steering Council, on the subject of @colesbury’s PEP 703 (Making the Global Interpreter Lock Optional in CPython). Thank you, everyone, for responding to the poll on the no-GIL proposal. It’s clear that the overall sentiment is positive, both for the general idea and for PEP 703 specifically. The Steering Council is also largely positive on both. We intend to accept PEP 703, although we’re still working on the acceptance details. As we’ve done a few times in the past, we ...
