My reason for adding [Either a b] -> ([a],[b]) is that at least two independent projects from independent authors use it and it seems generally widely useful. Althought techinically I don't have the same evidence for lefts and rights, I believe such evidence exists. At least one instance is for specifying the behaviour of unzipEithers, which is why I include it in the same patch.
Well since f x = (lefts x, rights x), why not name f "leftsAndRights", or "boths", or some such? -- Aaron Denney -><-
