ah, SliceStable does make it a little easier at least. I'd say you could just wrap that in a function, but you can't easily do that.

Sorting is probably the one area where I really miss generics in go.. because comparing and sorting IS such a generic thing to do. In my head I think, "Oh, so I just want to do

  hosts.sort(key=operator.attrgetter("os", "version", "address"))

and then proceed to write the 20 lines of code that lets me do that :-(
