Fix our API, so that QStringList and QList<QString> are the same thing. This required a bit of refactoring in QList and moving the indexOf(), lastIndexOf() and contains() method into QListSpecialMethods. In addition, we need to ensure that the QStringList(const QString&) constructor is still available for compatibility with Qt 5. Once those two are done, all methods in QStringList can be moved into QListSpecialMethods<QString>.
