I like the concept, but not the name. Inverse (or Inv) would be a better name imho.

What do people think of moving it to (or re-exporting it from) Data.Ord? Moving it would be nicer, but the fancy list comprehension desugaring might want it in GHC.Exts, so I'm not sure what the consequences would be.
