hmmm, I will concede that the currently required method will
require an extra copy.

I did briefly consider this, but it seemed it wasn't worth it. My
real main objection was that it broke the symetry of the load/save
system. I have found this symmetry is very helpful to permit
verification that serialization is correctly used. Also, my "thought
experiments" along these lines considered fundamental types
where copying was really an efficiency issue. Finally it
became clear that I couldn't figure out a way to handle
the versioning problem. So there you are
