using System;
using System.Collections;

class Test {
        public static IList Foo (Action<IList> action)
                ArrayList l = new ArrayList ();
                action (l);
                return l;

        public static IList Populator (IList list, IEnumerable items)
                foreach (object item in items)
                        list.Add (item);

                return list;

        public static void Main (string [] args)
                var list = Foo (l => Populator (l, args));

                foreach (object item in list)
                        Console.WriteLine (item);

Fails with:

[mono] ~/Desktop @ gmcs test.cs 
test.cs(22,28): error CS1502: The best overloaded method match for
`Test.Foo(System.Action<System.Collections.IList>)' has some invalid arguments
test.cs(5,29): (Location of the symbol related to previous error)
test.cs(22,28): error CS1503: Argument 1: Cannot convert type `lambda
expression' to `System.Action<System.Collections.IList>'
test.cs(24,17): error CS1579: foreach statement cannot operate on variables of
type `object' because it does not contain a definition for `GetEnumerator' or
is not accessible

That should compile and print to stdout all arguments passed to the executable.
