Bug report
runpy.run_path will accept a Path object, and run it, but various code inspection tools will be unhappy with it because it is not a string. Should run_path convert its argument to a true string before execution?
Coverage.py is one of those tools; this report is based on nedbat/coveragepy#1417.
Create debugme.py:
from pathlib import Path import runpy, sys runme = Path(__file__).resolve().parent / sys.argv[1] print(f"Running {runme!r}") runpy.run_path(runme)Create inspectme.py:
import inspect print(inspect.stack()) print('here')Run it:

I'm on a Mac, and this behavior seems consistent on versions 3.7 through 3.12.0a1.
