We already include the sources in py_srcs, and need to refer to them directly. By listing _vendor:stringcase as well, we were making a top-level stringcase library available, which would have only worked for distributing because the wheel definition was also incorrect. - mypy errors are what caused me to mistakenly add the above - they were because the type: ignore at the top of stringcase.py was causing mypy to completely ignore the file, so it was not aware of any attributes it contained.
