I think, this highly depends on data and the container.
What if data is stored inside the container? How the container 
can reference data if it is the one and only holder? In which 
format do you expect the container to release the raw data? How 
do you suppose to synchronize a data movement and references to 
it, if the container contains only references?
But what, if data may not be copied or moved, but the container 
manages the data by copy?
Is data assumed to be destroyed/invalidated after the container 
is destroyed? And why?
