data LineItem = LineItem { name :: Maybe String , quantity :: Maybe Quantity , price :: Maybe Price }
Rather than this definition, what about something like:
data LineItemF f = LineItem { name :: f String , quantity :: f Quantity , price :: f Price } It seems Wojtek already objected to this approach, though perhaps that objection could be overcome
Hmm, perhaps like this
LineItemFi = LineItemFi { name :: StringFi , quantity :: QuantityFi , price :: PriceFi }
data LineItemUi f = LineItemUi { name :: StringUi , quantity :: QuantityUi , price :: PriceUi }
You didn't use f there.
