I certainly agree that it's a nasty constraint.  I think I can see
only one way to achieve non-intrusive deserialization in portable C++:
the deserialization function gets an address into which the object
will be constructed with placement new.  The main downside of this
approach is that it becomes difficult to deserialize subobjects.
