I don't understand. What is the point of adding a new __fspath__
protocol to *implicitly* convert path objects to strings, if you still
have to use an explicit conversion?
I would really expect that a high-level API like pathlib would solve
encodings issues for me. IMHO DirEntry entries created by
os.scandir(bytes) must use os.fsdecode() in their __fspath__ method.
os.path.join() is just one example of an operation on multiple paths.
Look at os.path for other example ;-)
> os.path.join(*map(os.fsdecode, ("str", b"bytes")))
This code is quite complex for a newbie, don't you think so?
My example was os.path.join(pathlib_path, "str_path", direntry) where
we can do something to make the API easier to use.
I don't propose to do anything for os.path.join("str", b"bytes") which
would continue to fail with TypeError, *as expected*.
