title: LLVM&Clang support of C++11
body: <p>I have some code written by me for MS VC++10. I use C++11 and, in particular, expressions like </p>
  
  <pre><code>std::function&lt;int (int)&gt; f =...;
  auto it = v.begin();
  for_each(it1, it2,[&amp;](int&amp; i) { ++i;}); 
  </code></pre>
  
  <p>Now I'm trying out MacOS and XCode with llvm&amp;clang and my code can't be compiled! The question is why? Perhaps, I shall specify an option to use c++11. In this case, where can I fix it in xcode?</p>
