It seems like it would be reasonable for pathlib.Path to call fspath on the path passed to pathlib.Path.init, which would mean that if other libraries implemented fspath then you could pass their path objects to pathlib and it would just work

and then any lib that needed a path, could simply wrap Path() around whatever was passed in.

This is much like using np.array() if you want numpy arrays -- it works great.

numpy is trickier because they are mutable and can be big, so you don't want to make a copy if you don't need to -- hence the np.asarray() function -- but Paths are immutable and far more lightweight.
