Are you sure that doesn't work?  I swear I have been doing the same
with my collection classes.

>From ArrayListTest.ck:

class Foo
{
    fun int foo()
    {
        return 1;
    }
}

// unit test for ArrayList

class ArrayListTest extends Assert
{
    {
        true => exitOnFailure;
        testConstructor();
        testSize();
        testGetAddSet();
        testIterator();
        testForEach();
        testAssign();
        testTransform();
        testAddAll();
        testFoo();

        <<<"ArrayListTest ok">>>;
    }

//...

    fun void testFoo()
    {
        ArrayList list;
        Foo fooIn;
        list.add(fooIn);
        list.get(0) $ Foo @=> Foo fooOut;
        assertEquals(fooIn, fooOut);
        <<<fooOut.foo()>>>;
    }
}
