How about:

template < typename Iterator > class key_iterator : public get_iterator< Iterator , 0 > { public :

key_iterator() {}

key_iterator( const Iterator& i ) : get_iterator< Iterator , 0 >( i ) { } } ;

IIRC, a conforming iterator can't be implemented using inheritance. Overloaded operators would return the base type. -- Shunsuke Sogame
