IMHO it become especially interesting in terms of root_ptr if bar is a 
function which:
- stores object in a global variable,
- or affect it as property values to several different QML items with 
different lifecycles,
- or even send it to C++ through a signal the slot being able of calling 
QQmlEngine::setObjectOwnership() if it wants, or add the object as a 
global variable from C++ using, for instance 
QJSEngine::globalObject().setProperty().

Regards.
