implicit class CombinatorialList[A](l: List[A]) {
val xsize = l.size
def xcombinations(n: Int): List[List[A]] =
if (n > xsize) Nil

traitは線形だね ref: http://qiita.com/songfei1983/items/e2de97a63d88f8b4f9ab

関数合成 ref: http://qiita.com/songfei1983/items/c9df0bc8d5e199fba583
val add1: Int => Int = x => x + 1
val sq = (x: Int) => x * x
val add100 = (x: Int) => x + 100
foo map (add100 compose sq compose add1)
//res9: List[Int] = List(104, 109, 116, 125, 136)
//functionをリストにしたら、自由度高いじゃと思って！下記の方法を見つかった！
