Lets say I have a data type like so:

data IpAddress = IpAddress {$ o1 :: !Int,$ o2 :: !Int,$ o3 :: !Int,$ o4 :: !Int$ } deriving (Show)$

which you can create by doing: IpAddress 192 168 1 1

Is there a way to do the same thing with the input data in a list? Like: IpAddress [192,168,1,1]

or using some operator (or combination of operators):Like (I'm guessing (<????>) isn't in use): IpAddress <????> [192,168,1,1]

No, there isn't. But you can make a function ipAddress :: [Int] -> IpAddress ipAddress [a,b,c,d] = IpAddress a b c d -Brent
