Well, actually, QVector<void *> cannot contain unlike things. It can
contain only untyped pointers. Of course these can point to whatever you
want - unlike to what other pointers in the same QVector are pointing to
or not - but the pointers are still of the same type. Note that the
objects pointed to are also not contained in the QVector. They are
located somewhere else, not managed by the vector. So no, nothing like a
tuple at all.
