[New-bugs-announce] [issue37920] Support subscripting os.PathLike and make it valid at runtime

[Cameron Trando]

New submission from Cameron Trando <ctrando at ucsd.edu>:

Currently os.PathLike[str] causes a runtime error; however, typeshed sees it as valid and mypy does not throw any errors on it. 

mypy treats it as os.PathLike[AnyStr] 

I already filed a bug on typeshed, see https://github.com/python/typeshed/issues/3202

And since mypy interprets it as useful, cpython should try and support it as well.
