The current library report defines unionBy like this: unionBy eq xs ys = xs ++ deleteFirstsBy eq (nubBy eq ys) xs
why does it take the nub of ys, but not xs? I'd have expected unionBy eq xs ys = (nubBy eq xs) ++ deleteFirstsBy eq (nubBy eq ys) xs Jón -- Jón Fairbairn [EMAIL PROTECTED] 31 Chalmers Road [EMAIL PROTECTED] Cambridge CB1 3SZ +44 1223 570179 (after 14:00 only, please!) _______________________________________________ Haskell mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell
