I currently have (C is indexed_set container type, c is instance of that 
container, T is index tag):
   const typename index_type<C,T>::type& myindex=get<T>(c);
   typename index_type<C,T>::type::const_iterator i=myindex.begin();

Does this become this?
   const typename index<C,T>& myindex=get<T>(c);
   typename index_const_iterator<C,T> i=myindex.begin();

Those are both shorter and more readable, so I like them.
