Well, that might be in general the case. But at least in my case I think
it does make sense: random_set_iterator is basically a
std::vector<>::iterator with the noteable difference that the
next-operation ++ is replaced by a function which moves the iterator to
a random element in within the vector. And as I do want to delete
elements from the vector which I find by the random-iterator, I need the
conversion.

Thanks, that did it.
