Hi all, In Lua I could do something like this: -- initialize empty table P = {} P.a = "bla1" P.b = "bla2" and so on. Now I can refer to each value by name, and I also can easily iterate over the table P. How can I do something similar in Haskell. Note: I do want only write each variable one time (or two times if I count the type definition). I thought about: data P = P { a :: String, b :: String } Then I have one definition pval = P { a = "bla1", b = "bla2" } Now I could refer to each val easily, e.g. a pval. However, I don't see that I could iterate over the members of pval. It there a way to do what I want without defining a list like this? pls p = [ (a p), (b p)] Perhaps a comletely different way? -- Manfred
