わーい、すごーい

クソだとはわかってる。でも速度が大事だから。ファーストペンギン。

case class Friends(message: String = "") {

  def wai() = {
    new Friends(this + "わーい")
  }
  def sugoi() = {
    new Friends(this + "すごーい")
  }
  def tanoshii() = {
    new Friends(this + "たのしー")
  }
  def friends(skill: String) = {
    new Friends(this + s"君は${skill}がとくいな、フレンズなんだね！！")
  }

  override def toString: String = message + "\n"
}

println(Friends() wai() sugoi() tanoshii() friends("scala"))
