The above would be a problem.  Serialization operators use reference to data 
as arguments.  An object pushed on the stack has no permanent address.  So 
it can't be serialized.

suppose you made the above work by doing something like:

    const int x = 0;
    ar << x;

If the above did work - that is if it inserted a 0 value into the archive, 
then what would loading mean?

So the question is - what is the intention here?
