And there's nothing stopping people from subclassing from Path (should
it be PurePath?), or monkey-patching pathlib. In this case,
"isinstance(foo, Path) returns true" is the protocol.

Also, where is the .path attribute? It's documented
<https://docs.python.org/3/library/pathlib.html#pathlib.PurePath.path>,
but...

>>> pathlib.Path(".").path
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'PosixPath' object has no attribute 'path'
