Could you maybe use RUF024 for this? I'm using RUF023 for #9564 :) |
|
Oops, I will change it when I am back at my desk |
|
Can you also open an issue on this for flake8-bugbear? I'm sure they'd love to include this rule and it would make more sense with a reserved B error code. Other ruff rule suggestions have been added there and we usually migrate the rule alias. |
|
Ah nvm, there is an issue that has been open for a while: PyCQA/flake8-bugbear#387 |
