title: Equivalent of "description" for a C++ class in Objective-C++?
body: <p>I want to be able to debug objective-c++ code which contains instances of a c++ class quickly.</p>
  
  <p>With objective-c classes, I can simply implement <code>description</code> to return a human readable string, and then when I <code>po var</code> in lldb I immediately know anything I need to know about the instance.</p>
  
  <p>Is there any way I can achieve this for c++ classes used from objective-c++ code as well?</p>
