[Haskell-beginners] How to show a record

[martin]

Hello all,

I have a record type like this

	data Payload = Pl {
        	    pType    :: Char,
	            accepts  :: String,
        	    produces :: String,
	            workarea :: String} deriving (Eq)

an I want to write my own show function. I ended up with somethink like this

	show pl = concatMap ( $ pl) [show . pType, show . accepts, show . produces, show . workarea]

That repetition of "show ." annoys me, but of course without it the elements of that list would have different types. Is
there a way around it and how does haskell itself manage to show records?
