Hi @unterumarmung, thank you for pointing the policy out as I wasn't aware of it. Yes, I used Claude as an AI assistant during development. I reviewed all the generated code and made sure I understand all of it before committing any changes to this PR.

Also, I added test cases for comments before, after, and inside the parentheses.
