Since you have declared the constructor as private, maybe you should also declare the class as final.

    private $name;
    private $aggregateId;

    public static function fromName(string $name) : self
    {
        list($name, $aggregateId) = explode('-', $name, 2);

        return new self($aggregateId, $name);
    }

    {
        return new self($aggregateId->id(), $name);
