New submission from Roy Williams <rwilli...@lyft.com>:
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/ ?
