title: copy vs std::move for ints
body: <ul>
  <li>What's difference between default copy and std::move in that example?</li>
  <li>After <code>move</code> the object is there any dependence between new and old ones?</li>
  </ul>
  
  
  
  <pre><code>int main () {
  
      int a = 100;
      std::cout&lt;&lt;&amp;a&lt;&lt;std::endl;
  
      auto a_copy = a;                 // deduced as int
      std::cout&lt;&lt;&amp;a_copy&lt;&lt;std::endl;
  
      auto a_move = std::move(a);      // deduced as int
      std::cout&lt;&lt;&amp;a_move&lt;&lt;std::endl;
