A lot of the Java ORMs have this approach to optimistic locking built in,
but as far as I can see, none of the Perl ORMs do. I tried looking at the
internals of DBIx::Class to figure out how to add support for this as a
component, but basically got swamped by the details - I couldn't figure out
how to trasparently compare the version numbers. But if anyone has any ideas
on how to do this if anyone has got any pointers...
