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

 In [changeset:3229eadbff857b110f20ffddb80d5f7abd5d7216/ghc]:

 revision="3229eadbff857b110f20ffddb80d5f7abd5d7216"
 Fix GHCi macros not shadowing builtins (#8113)

 This restores the original behaviour that was broken accidentally during
 the refactoring peformed via 4f764d06f3b9899c09a6a459a22d4be694ee45d9.

 This has been broken effectively for all GHC 7.6.x releases.
