title: Is there any use for unique_ptr with array?
body: <p><code>std::unique_ptr</code> has support for arrays, for instance:</p>
  
  <pre><code>std::unique_ptr&lt;int[]&gt; p(new int[10]);
  </code></pre>
  
  <p>but is it needed? probably it is more convenient to use <code>std::vector</code> or <code>std::array</code>.</p>
  
  <p>Do you find any use for that construct?</p>
