darcs patch: Control.Monad: +void :: f a -> f ()

Not sure if this came up already, but there is a less general version
of void in Foreign.Marshal.Error:
http://www.haskell.org/ghc/docs/latest/html/libraries/base-4.2.0.0/Foreign-Marshal-Error.html#v%3Avoid
void :: IO a -> IO ()
Discard the return value of an IO action
Are there plans to unify the two? Perhaps Foreign.Marshal.Error can
just re-export void from Control.Monad?
