[Interest] How to avoid qml engine repeatedly copying and garbage collecting qstringlists?

That would be one way to do it. I don't know what your singleton looks 
like. Maybe it can be defined in QML and instantiate a non-singleton 
type declared in C++ rather than referencing yet another singleton. That 
would probably be faster.
