If I have the following code:

type Cell = Empty | Letter String

type alias Square =
  { cell : Cell
  , num : Int
  }

and c : Maybe Square,

can I do the following in a single match?

  case c of
    Just { cell } ->
      case cell of
        Letter s -> s
        _ -> ""
    _ -> ""

that is, i conceptually want

  case c of
    Just { cell = Letter s } -> s
    _ -> ""
