# A CakeType is a flavor, layers, & is-iceCream
data CakeType:
    | cake(____________________________________________________
           ____________________________________________________
           ____________________________________________________)
      end

To make an instance of this structure, I would write:

cake1 = ____________________________________________________

cake2 = ____________________________________________________

To access the fields of cake2, I would write:

        ____________________________________________________

        ____________________________________________________

        ____________________________________________________
