Those aren't even collected on older Pythons. What prompted this PR?

I was not able to find the part in the code that isolates these tests for older Python versions, hence this PR. Can you show me where this test is ignored for 3.10 in the current code?

What prompted this PR?

This library was packaged into Debian to ease Python version transitions. Debian is trying to switch to 3.11 for its next stable release. So currently both 3.10 and 3.11 version are supported in its rolling release flavor (unstable). This means that this package is currently tested against 3.10 and 3.11 in Debian. It failed to build on 3.10 because our automatic test runner executed this test_catch_py311.py file despite the version being 3.10. Hence this patch was introduced into the package for Debian.

Have a nice day.

Here: https://github.com/agronholm/exceptiongroup/blob/main/tests/conftest.py#L3-L4

If this wasn't present, the test suite would fail both locally and on GitHub.

automatic test runner executed this test_catch_py311.py

How are you running the tests if not via pytest?
