[Boost-users] [bimap] as relationship container

Firstly, I think the bimap library is great.

What would suit my situation is to use a container type of relation that
allowed storage of some information with each relationship.

Effectively: map_of_relation< UserDefineValueType, KeyComp > (and related
multimap, unordered_map, etc).

As a usage example, in database terms, TableA references TableB.

Attached to the TableA->TableB relationship, would be a bimap of rows in
TableA that reference rows in TableB.

So...

typedef
bimap<
  set_of<Rows:iterator>,
  set_of<Rows:iterator>,
  map_of< RelationshipDescription >
> RowRelationships;

typedef bimap<
  multiset_of<Table::Ptr>,
  multiset_of<Table::Ptr>,
  map_of_relation< shared_ptr<RowRelationships> >
> TableRelationships;

Is this easy to add with the current bimap architecture?
