This works Ok for Qt because Qt is a well designed API. It wouldn't work for a 
badly designed API (with foo(QString *) and foo(const QString &)).

That said, this whole thing would be in addition to the current 
implementation - it would not be a replacement - so maybe it doesn't need to 
provide a solution to the "difficult" cases.
