1. error: unused 'type: ignore' comment
2. Module 'pywintypes' has no 'error' member
3. Module 'win32pipe' has no 'SetNamedPipeHandleState' member,
but source is unavailable. Consider adding this module to
extension-pkg-whitelist if you want to perform analysis based on
run-time introspection of living objects.
This allows us to add a docstring to .append() so users can see
the names of the arguments that are being passed, and means we
don't have to remember to prepend run_ when calling a hook.
