* summary: Add partitionEithers, lefts, rights to Data.Either => Add
unzipEithers, lefts, rights to Data.Either
Comment:
Everyone commenting so far now finds unzipEithers the best name for the
function `unzipEithers :: [Either a b] -> ([a],[b])`
There have also been suggestions of
`partitionEither :: (a -> Either b c) -> [a] -> ([b], [c])`
but this should go into a new trac if people want to pursue it.
