Re: [Haskell-cafe] Idiomatic Haskell equivalent of "keyword arguments" to functions

I looked at wxHaskell for inspiration - its approach (button f [text := "Quit", on command := close f]) looks quite readable, but slightly unusual (to me) for Haskell. It also seems fairly complex to implement (ie, my head hurt when I tried to follow the types involved, but maybe that's just because it's getting late :-))

I forgot one - it's extensible, so if you want to add extra parameters you don't need to change the type of the function, and you don't need to change every single call site either. -- -David House, dmhouse@gmail.com
