#### Частичное применение
Когда метод вызывается с меньшим количеством списков параметров, то результатом будет функция,
которая принимает в качестве параметров недостающие списки. Это официально известно как
[частичное применение](https://ru.wikipedia.org/wiki/%D0%A7%D0%B0%D1%81%D1%82%D0%B8%D1%87%D0%BD%D0%BE%D0%B5_%D0%BF%D1%80%D0%B8%D0%BC%D0%B5%D0%BD%D0%B5%D0%BD%D0%B8%D0%B5).

Например,

```tut
val numbers = List(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
val numberFunc = numbers.foldLeft(List[Int]()) _

val squares = numberFunc((xs, x) => xs :+ x*x)
print(squares) // List(1, 4, 9, 16, 25, 36, 49, 64, 81, 100)

val cubes = numberFunc((xs, x) => xs :+ x*x*x)
print(cubes) // List(1, 8, 27, 64, 125, 216, 343, 512, 729, 1000)
```
