I just stumbled over a FTP breakage: A RULES with "foldr" on the left hand side would no longer fire, because it would refer to Foldable.foldr, and not the monomorphic foldr.
Adding #if MIN_VERSION_base(4,8,0) import Prelude hiding (foldr) import GHC.OldList (foldr) #endif to the file solved the problem for now, but GHC.OldList is supposed to go away eventually, so I believe we need a permanent location for the monomorphic foldr.
in (accidentally?) private communication, Herbert suggested to use GHC.List, which also exports foldr. GHC.List does not show up in the haddock index, but does exist, and is likely to stay.
