I'm not aware of anything in the library. You can define a utility implicit conversion and class that you can import as needed.

class TimesRepeat(n:Int) {
  def timesRepeat(block: => Unit): Unit = (1 to n) foreach { i => block }
}
object TimesRepeat {
  implicit def toTimesRepeat(n:Int) = new TimesRepeat(n)
}

import TimesRepeat._

3.timesRepeat(println("foo"))
