:( What a shame. For dinkumware stl (for VC6.5) it is possible to write a more specialized metafunction: is_stl_iterator<> as the relevant iterators has a common base class (vector<T> uses T*) Is this also feasible for other stl-implementations? Of course, this would only solve the problem for stl containers. The question is whether this is a common enough usage that it is advisable to implement support for it. Peder
