Hi all, I was wondering if there is syntactic sugar in Haskell for defining a default value for fields in a data type. For instance, say I have a type that is defined in record syntax: type CustomerID = Int type Address = Maybe String data Customer = Customer { customerID :: CustomerID , customerName :: String , customerAddress :: Address } deriving (Show) Is there any way to define default values for some (or all) fields such that they may be omitted from a declaration, and still have it generate a valid object? e.g.) a = Customer{customerID = 12, customerName="Bill"} -- I would like a{customerAddress} to default to Nothing (for instance). It seems to me that this would be a nice feature to have, if it does not exist. Am I missing something? Mike
