Comment:
Not fully fixed yet. I just observed this when compiling `mono-
traversable-0.6.2` using GHC-7.8.4-rc1:
{{{
[2 of 7] Compiling Data.MonoTraversable ( src/Data/MonoTraversable.hs,
dist-ghc/build/Da
ta/MonoTraversable.o )
src/Data/MonoTraversable.hs:39:1: Warning:
The import of `$, replicate' from module `Prelude' is redundant
makeCorePair: arity missing $cofoldMap{v aaQ1} [lid]
}}}
