I think that PurePath.__fspath__ should return a string. There’s no
reason why we can’t in my opinion and doing so just limits the usefulness
of the method. For instance, it’d prevent it from being possible to
serialize a pure windows path and send it over the wire to a process running
on a Windows machine, like say if you have a build master running on Linux
and a build slave running on Windows.
