/**

trait DeprecatedTraits
{
    /**
     * @param $key
     * @return bool
     * @deprecated Use ->has($key) instead
     */
    public function exists($key)
    {
        return $this->has($key);

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

    }
