@Itay, I agree. You can make a list immutable of course (Collections.unmodifiableList), but that would be missing the point :-)

It would be nice to have a Scala/Java utils library for java code that needs to use Scala list for language interoperability or just because its nice. List$.MODULE$.fromArray looks too much like hacking or using unsupported implementation.

Creating a Scala list from Java isn't obvious, but certainly doable.

import scala.List;
import scala.List$;

public class Test {
public static void main(String[] args) {
List<String> ducks = list("huey", "duey", "louie");
}

public static <A> List<A> list(A... args) {
return List$.MODULE$.fromArray(args);
}
}

"Scala's List is not a Java Collection list.".

I guess you could blame immutability. In fact, I really wish Java had an immutable (you know, Lisp-like) list.
