@SolitudeSF, I just created P.R. #1569 that implements a `dedupe` command. So now we can efficiently sort lists with duplicate elimination and dedupe arbitrary inputs.

There was an IM/Gitter discussion about this wherein @xiaq pointed out that preserving insertion order is often more useful than sorting the map's keys. Which is why Python's `collections.OrderedDict` exists...
