   That's the bit I'm not sure does work. If, for instance d* is passed to a   
   separate translation unit before serialisation, the compiler can't tell   
   whether d is pointing to an individual double or an array of doubles.   
      
   At this point there's little choice but to serialise the entire allocated   
   block that d points into.   
      
   Though, the serialisation can be done naively, since clearly it cannot   
   contain anything other than doubles that would need to be valid on the   
   other end.   
      
   I'm not actually 100% sure about that last point. If you can legitimately   
   construct a pointer to a   
      
   struct NotSure{   
   	double first_member;   
   	//other stuff   
   };   
      
      
   from a pointer to a double then you can't even assume that the only data   
   pointed to is doubles. I can't remember if this is legal in C++ off hand.
