       s1 = os.stat(f1)
   TypeError: argument should be string, bytes or integer, not WindowsPath

   Converting to str() works but is unexpected.

   This is a specific example of a global discussion about handling of paths in the stdlib. So far we have elected not to provide special handling. The correct thing to do is call str. I'm not sure if shutil is special enough to be a special case, but it would need to be discussed in the context of the larger issue in some forum other than the bug tracker (probably python-dev).

   Is this issue outdated since implementing a file system path protocol (PEP-519) in 3.6?

   I'm unable to reproduce the bug on Python 3.6:
   ---

   from pathlib import Path
   import shutil
   import os
   def touch(name):
       with open(name, "x"):
           pass
   os.mkdir('a')
   touch('a/x')
   touch('a/y')
   touch('a/z')
   os.mkdir('b')
   source_path = Path('a')
   destination_path = Path('b')
   for file_name in source_path.glob('*'):
       file_name = file_name.name
       src = source_path / file_name
       dst = destination_path / file_name
       print("%r -> %r" % (src, dst))
       shutil.copyfile(src, dst)

   ---

   Output:
   ---
   PosixPath('a/y') -> PosixPath('b/y')
   PosixPath('a/x') -> PosixPath('b/x')
   PosixPath('a/z') -> PosixPath('b/z')
   ---

   Thank you PEP-519 ;-)
