title: Does C++11 standard provide something like boost::any?
body: <p>for example <code>boost::function</code> is moved almost entirely to <code>std::function</code>, the same is with <code>boost::shared_ptr</code></p>
  
  <p>But I can't find <code>std::any</code>?
  Was it renamed or was not it placed in new standard at all by any reason?</p>
