Hello,

I've noticed that when type hinting paths, it often becomes a bit verbose:

from typing import Union
import pathlib 

custom_path = Union[str, pathlib.Path]

def foobar(x:custom_path):
   ...
Writing functions which handle paths are pretty routine, I'm wondering if it is worth including something that is importable e.g.

from typing import PathLike #or similar path_obj, PathType etc. 
def foobar(x:PathLike):
 ...

Apologies if similar functionality already exists,

Alex

I just noticed this issue was raised and dismissed in  PEP 519 -- Adding a file system path protocol.
