Subject: Build mypyc wheels for CPython 3.11 (#3276)
X-Git-Url: https://git.madduck.net/etc/vim.git/commitdiff_plain/75d5c0e3fbf5de67b995c80e12229b7525ff6bb9?ds=inline;pf=etc

Build mypyc wheels for CPython 3.11 (#3276)

Bumps cibuildwheel from 2.8.1 to 2.10.0 which has 3.11 building enabled
by default. Unfortunately mypyc errors out on 3.11:

src/black/files.py:29:9: error: Name "tomllib" already defined (by an import)  [no-redef]

... so we have to also hide the fallback import of tomli on older 3.11
alphas from mypy[c].
