title: Enable std::get support on class
body: <p>What are the templates that I have to specialize to support std::get?</p>
  
  <pre><code>struct MyClass {
    int a;
  };
  
  template &lt;const size_t I&gt;
  struct MyContainer {
    MyClass array[I];
  };
  </code></pre>
  
  <p>What do I have to specialize to be able to do:</p>
  
  <pre><code>MyContainer&lt;16&gt; mc;
  std::get&lt;0&gt;(mc);
  </code></pre>
