title: Non-static Data Member Initializers / Calling constructors of std::vector
body: <p>Code:</p>
  
  <pre><code>class A {
    std::vector&lt;int&gt; x = {2,3};                 // x[0] = 2 and x[1] = 3
    std::vector&lt;int&gt; y = std::vector&lt;int&gt;(2,3); // x[0] = 3 and x[1] = 3 Too verbose!!  
  };
  </code></pre>
  
  <p>Is there a way that I can call the constructor of <code>std::vector&lt;int&gt;</code> only using brace initializer, or at least shorter version which gives the same effect?</p>
  
  <p>I don't want to repeat <code>std::vector&lt;int&gt;</code>. </p>
