I know that mostly this is checked by phpstan/psalm, but I think it will be good to double check this on phpcs level

@vladyslavstartsev Sure, let's open a PR for that.

Could you do it?

@carusogabriel 🤦 this is not already released, it will be when slevomat/coding-standard 6.3.0 will be done

[kukulich]

I want to write one more sniff and then release 6.3.0.
