Couldn't this be easily done in userland with the ArrayLikeObject (an

example in the RFC) or something similar, just done as a trait? Maybe
having an example trait implementation that basically "imitates"
stdClass in terms of dynamic properties would be helpful to show in the
RFC, to highlight a possible resolution path for legacy code with this
problem. This could be an example implementation:

trait DynamicPropertiesTrait
{
     private array $dynamicProperties = [];
     public function &__get(string $name): mixed { return
$this->dynamicProperties[$name]; }
     public function __isset(string $name): bool { return
isset($this->dynamicProperties[$name]); }
     public function __set(string $name, mixed $value): void {
$this->dynamicProperties[$name] = $value; }
     public function __unset(string $name): void {
unset($this->dynamicProperties[$name]); }
}
