I've always called my local definitions of this function `sortOn`. I also frequently define `groupOn`.

Oh yes, 'sortOn' is a really nice name. :) _______________________________________________ Libraries mailing list Libraries@haskell.org http://www.haskell.org/mailman/listinfo/libraries

Huh, that name just reminded me of GHC.Exts.sortWith: http://hackage.haskell.org/package/base-4.6.0.1/docs/GHC-Exts.html#v:sortWit... Which actually has the right type signature, but it's still implemented as compare (f x) (f y), and for good reasons too in this case.
