title: IDEA "never accessed" warning on increment operator ++
body: <p>IDEA shows a warning if a increment <strong>int</strong> with <strong>++</strong> or <strong>+=</strong> operators.
  It can only be fixed if I increment in a explicit way <strong>int=int+1</strong>.</p>

  <p>Is it a bug or a feature?</p>
  
  <p><strong>EDIT:</strong> Ok, it's a feature of IDEA. But it seems to me wrong. We obviously can't increment something without accessing the initial state. Would we have operator overloading we can think of <strong>++</strong> as of a function with argument <strong>i</strong>.</p>
  
  <p>So, the question is: is it possible to change this behavior in IDEA?</p>
