I have noticed a problem with the following code.

from pathlib import Path

class PPath(Path):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

test = PPath("dir", "test.txt")

This gives the following error message.

Traceback (most recent call last):
  File "/Users/projetmbc/", line 14, in <module>
    test = PPath("dir", "test.txt")
  File "/anaconda/lib/python3.4/", line 907, in __new__
    self = cls._from_parts(args, init=False)
  File "/anaconda/lib/python3.4/", line 589, in _from_parts
    drv, root, parts = self._parse_args(args)
  File "/anaconda/lib/python3.4/", line 582, in _parse_args
    return cls._flavour.parse_parts(parts)
AttributeError: type object 'PPath' has no attribute '_flavour'

This breaks the sub-classing from Python point of view.

There is an ugly hack to sub-class Path but it's a bit unpythonic.
