Ok, I take the bait: QList is primarily a list, not an array (thus the name). That means that, by default, references to elements in the list are never invalidated until the element is removed again. The problem started when someone optimised QList to contain the elements in an array, but only for *some* types. So, depending on the type and the QTypeInfo for that flag, QList is either like a std::list or like a std::vector (QLinkedList / QVector in Qt speak). And it takes great mental discipline to use it in the proper way, and the resulting code will be highly fragile and/or extremely inefficient.
