Tail-recursive bounded stream of pairs of integers (Scala)?

Question

I\'m very new to Scala, so forgive my ignorance! I\'m trying to iterate of pairs of integers that are bounded by a maximum. For example, if the maximum is 5, then the iterat

Maybe an Iterator is better suited for you?

class PairIterator (max: Int) extends Iterator [(Int, Int)] {
  var count = -1

}

val pi = new PairIterator (5)
pi.take (7).toList
