New submission from Nikita Sobolev <mail at sobolevn.me>:
When trying to import both `windows_events` and `windows_utils` on non-Windows, they both fail.
But, they fail differently. `windows_utils` produces a good error message, whil `windows_events` produces a strange one.
Good:
```
Python 3.11.0a3+ (heads/main:8d7644fa64, Dec 30 2021, 13:00:40) [Clang 11.0.0 (clang-1100.0.33.16)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import asyncio.windows_utils
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/sobolev/Desktop/cpython/Lib/asyncio/windows_utils.py", line 6, in <module>
raise ImportError('win32 only')
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ImportError: win32 only
```
Not so good:
```
>>> import asyncio.windows_events
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/sobolev/Desktop/cpython/Lib/asyncio/windows_events.py", line 3, in <module>
import _overlapped
^^^^^^^^^^^^^^^^^^
ModuleNotFoundError: No module named '_overlapped'
```
I propose to use the same error message `windows_utils` does.
