It would say table renamed but you can ignore it. Your sequence will be renamed.
Gee, this is a nice trick! So simple, yet so elegant.

And as I can see it now from the documentation it is even documented! So besides tables and views (for which most of us was aware of, I gues) you can use RENAME also for sequences and for private synonyms.
