-            Hi everyone! This issue has been automatically closed due to inactivity.
-            If you think this issue is still relevant in the latest Solidity version and you have something to [contribute](https://docs.soliditylang.org/en/latest/contributing.html), feel free to reopen.
-            However, unless the issue is a concrete proposal that can be implemented, we recommend starting a language discussion on the [forum](https://forum.soliditylang.org) instead.
