It seems like it would be reasonable for pathlib.Path to call fspath on the

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.
