Present

Petr, Florian, Simon, Du Toit, Stepan, Antonio

C API Conference Workshop Recap

• We should have organized it earlier
• Antonio thinks we failed a bit on getting people from different groups together
• Stepan still had a lot of good discussions with people and learned about how they use the C API.
• Also: HPy was mentioned in several talks on the main conference
• Stepan also talked to Mark Shannon about an optimization that uses tagged pointers internally (see https://github.com/faster-cpython/ideas/pull/687/files) but needs to be reverted if pointers are handed out to C extensions. This is also related to PEP 703).
• Marks Shannon was not against offering some additional C API that would enable to use tagged pointers in C exts. However, this really would need to be started by someone from us.

Cython/HPy

• Du Toit and Stepan talked to David Woods about Cython upstreaming
• He was very open to that and we should start creating small PRs
• Du Toit is also giving a talk about his work at PyConZA
