Checklist

If this is a user-facing code change, like a bugfix or a new feature, please ensure that
you've fulfilled the following conditions (where applicable):

• You've added tests (in tests/) added which would fail without your patch
• You've updated the documentation (in docs/, in case of behavior changes or new
  features)
• You've added a new changelog entry (in docs/versionhistory.rst).

If this is a trivial change, like a typo fix or a code reformatting, then you can ignore
these instructions.

Updating the changelog

If there are no entries after the last release, use **UNRELEASED** as the version.
If, say, your patch fixes issue #999, the entry should look like this:

* Fix big bad boo-boo in the pytest plugin (#999 <https://github.com/agronholm/typeguard/issues/999>_; PR by @yourgithubaccount)

If there's no issue linked, just link to your pull request instead by updating the
changelog after you've created the PR.

To prove 3.15 compatibility, this should add 3.15 to the test matrix.

This isn't looking good, but I'm willing to give you a chance to fix it.

Please do not force push your changes. If you do, I won't know what you changed in response to my feedback.

[hrnciar]

I am sorry, I was about to reply in the above conversation.

[agronholm]

You added 3.15 to tox configuration but it's still missing from the Github Actions workflow.

Alright, getting better! Is there any place where the new fullname argument could be passed to?

From the 3.15 documentation:

Many functions related to compiling or parsing Python code, such as compile(), ast.parse(), symtable.symtable(), and importlib.abc.InspectLoader.source_to_code(), now allow the module name to be passed. It is needed to unambiguously filter syntax warnings by module name. (Contributed by Serhiy Storchaka in gh-135801.)

In our case, it could be used in the two _call_with_frames_removed calls (ast.parse and compile).

If you could do that on 3.15, that'd be great.

Looks like I introduced mypy errors with my simplification. Those need to be undone. Otherwise this looks good now!

Thank you for the help!
