Hello, is there way to declare read only field for class type
with ability to call inner non constant methods? i.e.:
> class A {
> int value = 12;
> void updateValue() {
> value = 13;
> }
> }
>
> class B {
> const A a;
>
> this() {
> a = new A();
> a.updateValue(); // error: mutable method is not
> callable using const object
> }
> }
