Thanks

FWIW: For PHP 8.4 you might want to consider just using the original Closure name as-is. My understanding is that this code attempts to do what PHP 8.4 now natively does and arguably does better.

This change would require raising the minimum php version requirement for this package

I just looked at your patch and the immediate context (i.e. no tests or so). Would a PHP_VERSION_ID < 80400-check not work?

This package does not support nor tests PHP 8.4 yet. I'll look at it again once I add official support, thanks
