Perhaps I misunderstand you. Cannot you do this?

template <class T, class IndexType = int> class QList {}?

That would, if I am correct, enable this:

QList<int> myNormalList;
QList<int, qint32> mySecondsNormalList; //equivalent to the above, on
platforms where int == qint32
QList<int, qint64> myHugeList;

The first is 100% source compatible with the current form, is it not?
