Abstract properties (hooks) in traits

Description

At the moment such code does not work (8.4 and 8.5/master), which does not seem very logical:

<?php

trait Example
{
    abstract public string $property {
        get; 
    }
}

class ExampleImpl
{
    use Example;
    
    public function __construct(
        public readonly string $property,
    ) {}
}

Produces:

Fatal error: ExampleImpl and Example define the same hooked property ($property) in the composition of ExampleImpl. Conflict resolution between hooked properties is currently not supported. Class was composed

According to RFC (https://wiki.php.net/rfc/property-hooks#interaction_with_traits), traits do not actually support properties, but at least such primitive conflict resolution would be nice to have.

P.S. Is it worth writing to internals for RFC if there is no way to send a PR?

Commencez par le reproducteur fourni de trait et de hooked property, puis lisez la section du property-hooks RFC consacrée à l’interaction avec les traits. Suivez la manière dont la composition de traits gère l’abstract hooked property et la implementing constructor-promoted property. Le travail est terminé lorsque l’exemple se compose sans le conflit signalé tout en préservant le comportement prévu du property-hook.
