On the other hand, the constructor could allow all input iterators but then choose the best applicable algorithm at compile time based on std::iterator_traits::iterator_category. I suppose that would be better. --- [ comp.std.c++ is moderated. To submit articles, try just posting with ] [ your news-reader.
