New submission from Zac Hatfield-Dodds <zac.hatfield.do...@gmail.com>:
Testing Hypothesis with Python 3.11.0a3, I've triggered a frustrating
regression in importlib.resources:
# Both work in Python 3.9 and 3.10, but both fail in 3.11.0a3
from importlib.resources import files, read_text
read_text("hypothesis.vendor", "tlds-alpha-by-domain.txt")
files("hypothesis.vendor").joinpath("tlds-alpha-by-domain.txt").read_text()
Traceback (most recent call last):
...
File "example.py", line 4, in <module>
read_text("hypothesis.vendor", "tlds-alpha-by-domain.txt")

File "python3.11/importlib/_adapters.py", line 141, in open

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
FileNotFoundError: Can't open orphan path
At first I thought this was just a problem with the _legacy shims, but since it
also affects the new files() API it might be more serious.
