btw, what I've been missing even more than isLeft/isRight is something like
leftMaybe :: Either a b -> Maybe a leftMaybe (Left x) = Just x leftMaybe _ = Nothing
rightMaybe :: Either a b -> Maybe b rightMaybe (Right x) = Just x rightMaybe _ = Nothing
These seem to be more useful for me than isLeft and isRight.
However, I think I would prefer maybeLeft and maybeRight.
