Found some issues in the eosio.token docs. First off, it says transfer instead of close (transfer is there twice)
Secondly, and more important, the retire action actually isn't the opposite of create, it's the opposite of issue. This has serious implications as it's saying in the docs you can un-create a token, and that isn't the case.
I just created a token and was trying to change the supply by using the retire option, but it doesn't clear the record from the stats table, so you can't make a new token with the same name, as implied in the docs.
