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.
