Why does Scala provide both multiple parameters lists and multiple parameters per list? [duplicate]

by

It makes you able to do e.g.:

scala> def foo(as: Int*)(bs: Int*)(cs: Int*) = as.sum * bs.sum * cs.sum
foo: (as: Int*)(bs: Int*)(cs: Int*)Int

scala> foo(1, 2, 3)(4, 5, 6, 7, 9)(10, 11)
res7: Int = 3906
