Hi. I am kind of tired of all of the parentheses I have to put in places and I'm trying to figure out what is the correct way to write code such that I can leave out parentheses. For example, I have the following: data Message = ... --leaving this out because it's not important data Plane = Plane { id :: Int, position :: (Int,Int,Int), direction :: Int, path :: [Int], messagebuf :: Chan Message } main = do c <- newChan :: Chan Message p <- Plane 0 (0,0,0) 0 [] c f p f p = putStrLn $ (show Main.id p) ++ " - message received" This causes an error "The function `show' is applied to two arguments". If I put instead: f p = putStrLn $ (show . Main.id p) ++ " - message received" I get the error "Couldn't match expected type `[Char]' with actual type `a0 -> c0'". The only way it seems to work is f p = putStrLn $ (show (Main.id p)) ++ " - message received" This seems to be the same for many other situations where I try to use function composition of some sort. It's just getting kind of annoying. -Eitan
