    You don't cast them. You call the base() method to get (ahem) the base
    iterator that reverse_iterator adapts.

        typedef std::list<MyType> tList;

        tList MyList;

        tList::reverse_iterator lRItr = MyList.rbegin();
        tList::iterator lItr = lRItr.base();

        assert( lItr == MyList.end() );

    Nope.
