Return const object through mutable Object

[Jacob Carlborg]

class Foo
{
    Foo f;

    Foo bar () const
    {
        return f;
    }
}
The above code results in the compile error:

Error: cannot implicitly convert expression (this.f) of type const(Foo) 
to test.Foo

But if I change "bar" to:

Object bar () const
{
    return f;
}

I don't get any errors. Is the last example supposed to compile?

I'm using DMD v2.059.
