title: CQRS - Multiple command/query-handlers inside eachother
body: <p>Is it a good practice in CQRS to use multiple queryhandlers and/or commandhandlers in each other? Or should you only have one per use-case?</p>
  
  <ul>
  <li>Commandhandlers in a commandhandler</li>
  <li>Queryhandlers in a commandhandler</li>
  <li>Queryhandlers in a queryhandler</li>
  <li>Commandhandlers in a queryhandler -> personally, I wouldn't do this, because you won't expect a query should change data... Correct?</li>
  </ul>
