title: negation of std::integral_constant<bool>
body: <p>Sorry for asking so simple question, but I cannot find the answer easily. Google says nothing interesting about "C++ negation integral_constant" and similar queries.</p>
  
  <p>Is there in C++11 any trait that make <code>std::true_type</code> from <code>std::false_type</code> and vice versa? In other words, I'd like some more readeble version of</p>
  
  <pre><code>std::is_same&lt;my_static_bool, std::false_type&gt;
  </code></pre>
  
  <p>I know of course I can write it myself, but I'd like to use the existing one if there is such.</p>
