Hi All, I would like to request review of following PR: https://github.com/cython/cython/pull/5386 PR is not complex and is important because of two reasons: 1. It blocks PR https://github.com/scipy/scipy/pull/18242. Hence, it will allow us to have Cython 3 Beta in scipy which can help us test Cython 3 better (already 2 bugs were found during migration) 2. It seems it will break several libraries so I think it is better to have it in master earlier to give users more time for fixing issues. Thanks, Matus
