I recently switched to Quick question that's been bugging me - I'm working on a project and hit a roadblock. I'm working with a strange scenario when using traits that contain final methods in my PHP 8.2 application. I have a trait that provides some common functionality, including a final method that is supposed to be used directly by any class that uses the trait. However, when I try to extend that class with another class, I get a `Fatal behavior: want to override final method` message. Here's a simplified version of what I've implemented: ```php trait CommonTrait { final public function finalMethod() { return 'This is a final method.'; } } class BaseClass { use CommonTrait; } class ExtendedClass extends BaseClass { // Trying to override the final method here public function finalMethod() { return 'Trying to override.'; } } ``` When I run this code, it results in a fatal behavior stating that I want to override a final method. I expected the final method to be inherited as is, but it seems like PHP is treating it differently. I've tried removing the final keyword, and that works fine, but I want to keep the final method. I checked the [PHP documentation](https://www.php.net/manual/en/language.oop5.traits.php) but didn't find anything that clarifies this behavior. Is there a workaround or a design pattern that allows me to use final methods in traits without running into this scenario? Any insights would be appreciated. My development environment is Windows. How would you solve this? This is for a microservice running on Ubuntu 20.04. Is there a simpler solution I'm overlooking?
