And how about a restart instead of resume? I have used try catch blocks =
as a type of transactional block, so I think it would be nice if I could =
restart the entire block instead of resuming from the last point where =
it failed:

$blue =3D 'blue';
try {
    $data =3D a($blue);
    b($data); // This throws the dataIntegrityException
    c();
} catch (dataIntegrityException $e) {
    $blue =3D 'is the new red';
    restart; // executes a(), b() and c() again
} catch (Exception $e) {
    rollback();
}
