scala - ジェネリック メソッドをジェネリック関数に変換する方法

Question

質問

メソッドのタイミングを関数に変換する方法は?

val timing = new StringBuffer
def timed[T](label: String, code: => T): T = {
  val start = System.currentTimeMillis()
  val result = code
  val stop = System.currentTimeMillis()
  timing.append(s"Processing $label took ${stop - start} ms.\n")
  result
}

以下は「エラー：見つかりません：タイプT」を引き起こします

val timing = new StringBuffer
val timed: (String, => T) => T = (label, code) => {
    val start = System.currentTimeMillis()
    val result = code
    val stop = System.currentTimeMillis()
    timing.append(s"Processing $label took ${stop - start} ms.\n")
    result
}
