What about serialVersionUID?
The serialVersionUID is allowed and taken into consideration ( sorry, I
accidentally omitted this important point ). Setting the serialVersionUID is
required, to be able to migrate from a record-like class to a record. Since the
former and latter will likely have different default serialVersionUID’s, if not
explicitly set ( which one is encouraged to do ).
So, what we'll need here is guidance for:
- compiler writers, what to generate if no svuid is explicitly specified;
- migrators, what to do when migrating from a class to a record.
