title: Naming conventions for using GCD intensively
body: <p>I just dived into the world of using dispatch_queue a little bit more intensively and was wondering if there are some <strong><em>naming conventions</em></strong> that should be used just for GCD objects, so that the code of the classes is then more easily <em>divided</em> into <strong>GCD</strong> and <strong>other Code</strong>.
  Or could it be that it is a bad idea to have separate naming conventions for GCD?</p>
