I'm just starting out in Scala. I find myself using tuple variables a lot.

For example, here's some code I wrote:

/* Count each letter of a string and return in a list sorted by character
 * countLetter("test") = List(('e',1),('s',1),('t',2))
*/
def countLetters(s: String): List[(Char, Int)] = {
  val charsListMap = s.toList.groupBy((c:Char) => c)
  charsListMap.map(x => (x._1, x._2.length)).toList.sortBy(_._1)
}

Is this tuple syntax (x._1, x._2 etc) frowned upon by Scala developers?
