Some time ago I was playing with something related, i.e. tuple_vector. A 
container holding tuple elements in separate containers and proving 
access through proxy references, tuples of refecences. AFAIU it's not 
exactly what you're talking about but it's in the same "class" of 
containers benefiting from data locality.
