Repro: ```python from pathlib import Path import subprocess subprocess.run([Path('/bin/ls')]) # Works Fine subprocess.run(Path('/bin/ls')) # Fails ``` The problem seems to originate from here: https://github.com/python/cpython/blob/master/Lib/subprocess.py#L1237-L1240 This file auspiciously avoids importing pathlib, which I'm guessing is somewhat intentional? Would the correct fix be to check for the existence of a `__fspath__` attribute as per https://www.python.org/dev/peps/pep-0519/ ?
