I think Path should neither subclass string nor tuple. It might behave
like a string or a tuple, but it shouldn't subclass, as that
unnecessarily constraints the implementation strategy.

In particular, it shouldn't subclass str, as you then could not
represent Unicode file names in a reasonable way anymore.
