trait VGOps

    /**

     * @return bool
     */
    public function has(string $name) : bool
    {
        return $this->offsetExists($name);

It seems like offsetExists() must be provided by classes using this trait. How about adding it as abstract method to this trait?

    }

    /**
     * @param string $name
     * @param mixed $default
     * @return mixed
     */
    public function get(string $name, $default = null)
    {
        return $this->$name ?? $default;
    }
}
