           Summary: 2.067: Error when 'this' used as ref parameter
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux

class Foo
{
    public int baz()
    {
        return bar(this);
    }
}

public int bar(ref Foo foo)
{
    return 0;
}

int main()
{
    return 0;
}

2.066 compiles without error, 2.067-b3 outputs:

test.d(5) function test.bar (ref Foo foo) is not callable using argument types
(Foo).
