title: Can we use type names as variable
body: <p>I've been wondering about this question for a long time :
  Can we use a type name as a variable name ?</p>
  
  <p>For example someone on a REST api called one of its variable "protected", is there a way to get it ? I'm developing an Android app, and the api return Json object. To accelerate the process i use the Gson library.</p>
