The serialization package under discussion only throws an
exception if the archive has been corrupted some way. So
any exception during de-serialization would either be a
non-recoverable programmer error or an exception invoked
by some other system such as I/o which might be recoverable.
I don't see why the deserialization process can't throw an
an exception an if that exception is something recoverable
appropriate action can't be taken.
That is, I don't see that de-serialization raises any issues
regarding exceptions that are not raised by exceptions
generally.
