I'll think about adding i.value() too. The reason that it is good to
have operator*() return something is that we don't need another layer around
algorithms to accomdate for the different syntax...so I can clone the values and
put them in a ptr_vector quite easily:

ptr_map<U,T> map = ...;
ptr_vector<T> vec( map.begin(), map.end() );
