Well, the order of fields only matters in boost::serialization because all the
current archive classes read in order from the serialized data. I assure you
that a serialization archive can be built that doesn't depend directly on
order. Essentially the archive would read and parse the data into an
intermediate structure (property tree might be good :-) and then responds to
the deserialization requests using a mapped based lookup instead of getting
the next data from the file. The same exact implementation can be used to
make a binding to a database buffer derived from an sql command -- this also
might not have the fields in the same order as the object being serialized.
Not providing support for this case was one of the reasons that
boost::serialization was orginally rejected.
