RFC: https://wiki.php.net/rfc/final_class_const
In the current implementation, we are allowed to override constants in both classes and interfaces,
although in PHP 7.4 it is forbidden to override constants in interfaces.
PHP 8.1 introduces a
finalmodifier for constants and changes behavior for interfaces, now overridingis allowed by default.
Thus, with the support for the
finalmodifier for constants, we will begin to match the PHP behavior.
