4095,add Applicative instance for Either,ross,,"The proposal is to add this instance to Control.Applicative:
{{{
instance Applicative (Either e) where
        pure          = Right
        Left  e <*> _ = Left e
        Right f <*> r = fmap f r
}}}
This is not the only possible instance for Either, but this one is compatible with the usual Monad instance.",proposal,closed,normal,Not GHC,libraries/base,6.12.2,fixed,,,Unknown/Multiple,Unknown/Multiple,None/Unknown,,,,,
