Your particular types do not require your annoying repetition beyond
[ show . pType, accepts, produces, workarea] with 1st show = (:[])

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? _______________________________________________ Beginners mailing list Beginners@haskell.org http://www.haskell.org/mailman/listinfo/beginners
