Wouldn't it make sense to include all the array diffing methods into this one to make it easier for developers?
Honestly, I don't have a good idea myself as this would potentially require combining the variadic argument with an optional flag (ARRAY_DIFF_KEY¹/ARRAY_DIFF_VALUE or ArrKeyValue::Key/ArrKeyValue::Value or the like and callable), that would preferably come after all the arrays as it is optional but this is not allowed in PHP, but maybe someone has a clever idea here 🤔
¹ like ARRAY_FILTER_USE_KEY and ARRAY_FILTER_USE_VALUE

Incidentally, I thought about this too, but I came to the conclusion that it would be better to add only the methods that the programmer really needs to Arr.
That's why I only added array_diff

Why would this be the only one?

This PR adds a new Arr::diff() method — a simple, expressive wrapper around PHP’s array_diff().
