Convert List[Any] to List[Int]
How can I convert
List(1, 2, "3")
to
List(1, 2, 3)
since List(1, 2, "3") is of type List[Any] and I can't use .toInt on Any.

Starting Scala 2.13 and the introduction of String#toIntOption, we can make @liosedhel's answer a bit safer if needs be:
// val l: List[Any] = List(1, 2, "3")
l.flatMap(_.toString.toIntOption)
// List[Int] = List(1, 2, 3)
