Going by the traffic over the previous months, I think that class aliases or extensible records would be higher on most peoples lists than views.
i think that proper views is a must for Haskell - "We are keen on abstraction, but pattern matching is so convenient that we break abstractions all the time. It's our dirty little secret. " we need views in order to stop dealing with concrete datatypes and start writing polymorphic functions. just imagine that the following definition sum [x] = x sum (x:xs) = x + sum xs may deal with *anything*, from strict list to patricia tree. isn't that great? -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
