Please expand functionality of QQmlListProperty with methods such as insert, remove, take, etc. Also, for that matter, please provide consistent accessor functions for all model types.

For example, after a list<QtObject>, a QList<QObject*> exposed from C++, a ListModel, etc. has been assigned to a QQmlListProperty, accessing the model data via the QQmlListProperty should be consistent (count, length, or size should all be available, so that internal implementation of classes using a QQmlListProperty do not require one type of list or another to work). Indexing techniques should all also be available (.get, .at, [i]) for the same reason.
