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 :-))
This is actually a really nice solution, if you think about it: 1) You don't have to memorise the order the parameters come in (you can put the parameters in any order in that list). 2) It's self-documenting, f arg1 arg2 arg3 doesn't say what arg1, arg2 and arg3 do, but this way you get an idea. 3) If you had a function in another language with 10 parameters, all of which are optional, but you want to specify the last one, you have to include the default values (which may involve looking up what they are) of the first 9; no such problems here. Try again to understand the typing, hopefully you'll see this is probably The Best Way. If you have any questions about the typing itself, just post them here. -- -David House, [EMAIL PROTECTED] _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
