// We want to decode _multiple things_ from _one row_
def combine[A, B](left: RowDecoder[A], right: RowDecoder[B]): RowDecoder[(A, B)] = ???
// For example, if we wanted to decode a `Debtor` we want this to work:
final case class Debtor(id: Int, name: String)
// Whip up a decoder using the decoders of the fields!
val debtor: RowDecoder[Debtor] = combine(RowDecoder[Int], RowDecoder[String]).map(Debtor.apply)
