Comment (by Herbert Valerio Riedel <hvr@…>):

 In [changeset:"5b8fa46ca37caa9ec83b217a697628135da34506/ghc"]:
 {{{
 #!CommitTicketReference repository="ghc"
 revision="5b8fa46ca37caa9ec83b217a697628135da34506"
 Add Data.Version.makeVersion & `IsList Version`

 These two facilities provide some means to avoid the double-breakage
 caused by
 first by the deprecation (see #2496), and then again by the actual future
 field-removal.
