Summary of changes
Noticed in python/typeshed#12215
According to https://github.com/PyCQA/flake8-pyi/blob/main/ERRORCODES.md#Y043 , that was a bad name to have as it implies a TypeVar. I've renamed the alias to a more fitting
_StrictInstallerType
(alternatively:_GenericInstallerType
)This would've been caught by https://docs.astral.sh/ruff/rules/t-suffixed-type-alias/ if it was explicitly marked as a type alias.
Explicitly marked all type aliases I could easily find with
TypeAlias
(available in Python 3.10, backported totyping_extensions
