There's something that bothers me about putting the path in an attribute rather than subclassing tuple. [...] How do you do slicing and joining? If Path subclasses object, it could be done there like in the first example. But if Path subclasses string, that API is taken:

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.
