[boost] [serialization] iterators to stl containers

Could boost::serialization developers give ideas how iterators to stl containers should be made serializable? Robert suggested that they be serialized after the container, they iterate over, gets serialized. So we would have A) code that serializes container B) code that serializes iterator I thought about defering B to execute in A using the Command pattern. So if B happens before A, B will send a function object to A and this object would be executed when A gets called. What problems might there be with this implementation? Ivan
