Actually, I wrote too much code in that "solution" ;). Just this would be
enough:
template< typename T >
struct intrusive_iter
{
typedef T type;
typedef intrusive_iter<typename T::type> next;
};
template<>
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).
