And update the RFC "Impact on Ecosystem" section? Small note: implementations usually use array_column(self::cases(), 'value') instead of array_map(static fn(self $c) => $c->value, self::cases()). and that's just normal, as it is 2x faster: https://3v4l.org/Q5AYg#v8.4.14 maybe mention it as well, or instead of the one you had it the examples, as this is usually how it can be found in libraries. -- Alex
