Normally (when you don't have another copy of the object somewhere
else), this will work fine:

my $cd = Music::CD->retrieve(1);
undef $cd;
$cd = Music::CD->retrieve(1);

However, that will fail without the undef line in the middle, because
$cd will never go out of scope.

Your refresh() looks like it would be useful to some people, and it's
not the first time someone has asked how to do it.

I think ref($obj) covers it.

That's correct, it will be added to the index when it gets fetched
again.
