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

 In [changeset:"0a290ca0ad599e40ca15a60cc988640f1cfcb4c2/ghc"]:

 Add new `Data.Bifunctor` module (re #9682)

 This adds the module `Data.Bifunctor` providing the
 `Bifunctor(bimap,first,second)` class and a couple of instances

 This module and the class were previously exported by the `bifunctors`
 package.  In contrast to the original module all `INLINE` pragmas have
 been removed.
