title: Bind object into variable Symfony
body: <p>Is there any possibility to bind Objects into Variable in Symfony 5 using Attributes?</p>
  <p>For example, I have class:</p>
  <pre class="lang-php prettyprint-override"><code>class Users 
  {
      private $servers; 
  }
  </code></pre>
  <p>I has property $servers. I want to bind some object to this class using Attributes with some functionality and validation.</p>
