JsonDSL vs. JsonAST

gistfile1.scala

("lotto" ->
  ("lotto-id" -> lotto.id) ~
  ("winning-numbers" -> lotto.winningNumbers) ~
  ("winners" ->
    lotto.winners.map { w =>
      (("winner-id" -> w.id) ~
       ("numbers" -> w.numbers))}))

// vs.

JObject(List(
  JField("lotto", JObject(List(
    JField("lotto-id", lotto.id), 
    JField("winning-numbers", lotto.winningNumbers), 
    JField("winners", 
      lotto.winners.map { w =>
          JObject(List(
            JField("winner-id", w.id),
            JField("numbers", w.numbers)))}))))))

/* Both generates:

{
  "lotto":{
    "lotto-id":5,
    "winning-numbers":[2,45,34,23,7,5,3],
    "winners":[{
      "winner-id":23,
      "numbers":[2,45,34,23,3,5]
    },{
      "winner-id":54,
      "numbers":[52,3,12,11,18,22]
    }]
  }
}

I'd prefer the third one below :) Would it be possible to make such an DSL in scala?

I'd prefer that too :) No way to make it work in Scala though.
