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?

Inizia con il riproduttore fornito per trait e hooked property, quindi leggi la sezione del property-hooks RFC sull’interazione con i trait. Traccia il modo in cui la composizione dei trait gestisce l’abstract hooked property e la implementing constructor-promoted property. Il lavoro è completo quando l’esempio può essere composto senza il conflitto segnalato, preservando al contempo il comportamento previsto del property-hook.
