Leaving aside the extra benefits intrusive containers can bring in,
the ability of getting an iterator from a pointer to the element is
implementable for regular multi_index_containers --matter of fact,
this feature is internally used in the preview 1.34 version of
Boost.MultiIndex I announced yesterday.
