Actually, I wrote too much code in that "solution" ;). Just this would be

    template< typename T >
    struct intrusive_iter
        typedef T type;
        typedef intrusive_iter<typename T::type> next;

    struct intrusive_iter<void_>
    template< typename T >
    struct intrusive_list
        typedef mpl::nested_begin_end_tag tag; // not required
        typedef intrusive_iter<T> begin;
        typedef intrusive_iter<void_> end;

No 'begin/end' specializations needed, and the 'tag' typedef is there only
to make some deficient compilers happy (Borland, in particular).
