Well, depends on the size of your rows, keeping lists of 1mil+ column
names will eventually become reeeeally slow (at least in ruby).

You only ever need to decrement/increment by one and that should be
pretty simple in almost all cases. Granted it was a little tricky for
TimeUUID, but we are talking bytes here, so there really is only 0-255
+/- 1. If you are talking ASCII just trim that range down a little.
