Hm, *ponders* Doesn't it do rather well without it, though?
I think an iteration should iterate over the dataset as it were at the point of the iteration initialization. If that isn't possible, at least the same index set.

Actually no, the multiset iterator currently doesn't keep a stack since it allows the multiset to be changed without loosing track. It'd be possible to store the stack if it locks the index part of the multiset, like the mapping iterator. It wouldn't be difficult to extend it with an option to allow that mode of operation. Maybe it should even be the default mode?
