* Adding a parent to an existing class isn't always possible, if it

described?
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]); }
}
