Hi Everyone, I've just written an RFC for final constants: https://wiki.php.net/rfc/final_class_const. The prior thread can be found at https://externals.io/message/114066 In my opinion, the main value proposition of this RFC are the following: - people can make their intention more clear that a constant shouldn't be overridden - it can help fix an inconsistency in the language - the engine can infer the value of a constant in case of references via late static binding Máté

As I've fully finished the implementation, I intend to bring this to a vote on Wednesday if no new concerns come up (besides the usual question about the usefulness of the feature). Máté

Interesting RFC Maté, thanks for bringing it. How would we know if a given constant is overwritable? Would we need something like `ReflectionConstant::isOverwritable()`?

Hi Gabriel, see https://wiki.php.net/rfc/final_class_const#reflection
> A `ReflectionClassConstant::isFinal()` method is added in order to be
able to retrieve if a constant is final. Regards =)
