Another kindFunResult panic
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
Replacing <$> 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.
Thanks!
