In Scala :
val a = List(97, 44, 67, 3, 22, 90, 1, 77, 98, 1078, 6, 64, 6, 79, 42)
val b = a filter (_ % 2 == 0)
or val b = a filter (e => e % 2 == 0)
or val b = a filter (e : Int => e % 2 == 0)
or val b = for (e <- a if (e % 2 == 0)) yield e
The first notation "_ % 2 == 0" has no boilerplate and Scala is statically
typed (unlike Python).
