title: Is there a std::noncopyable (or equivalent)?
body: <p>There's a <a href="http://www.boost.org/doc/libs/master/libs/core/doc/html/core/noncopyable.html">boost::noncopyable</a> and I have my own noncopyable class in my library.  Is there a std::noncopyable or equivalent knocking around in the latest C++ standard?</p>
  
  <p>It's a small thing but deriving from such a class makes the intention much clearer.</p>
