While working at the GHCi prompt, I left off a pair of parens, yielding:
> import Control.Applicative > import Control.Monad.Trans > :type \x -> (either (fmap Right) id) <$> lift $ x ghc: panic! (the 'impossible' happened) (GHC version 7.7.20130214 for x86_64-unknown-linux): kindFunResult <<details unavailable>> Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
<$> lift $ x with
<$> (lift $ x), which is what I'd meant, makes everybody happier. But as this happens in both 7.6.2 and 7.7.20130214, I thought I should do what it says and report it.
