Re: Qualified destructors / immutable objects

[anonymous via Digitalmars-d-learn]

I cannot find a way to actually modify immutable memory with it...

a.d:

class C {
  int a;

  this(int a) {
     this.a = a;
  }
}

struct S {
    int x;
    C elem = new C(42);

    ~this() {
        import std.stdio;
        writeln("mutable ~this()");
        x = 1;
        elem.a = 123;
    }
}

void foo() {
    S s2;
}

void main() {
    import std.stdio;
    immutable(S) s1;
    //  Error: cannot modify immutable expression s1.elem.a
    // s1.elem.a = 43;
    writeln(s1.elem.a);
    foo();
    writeln(s1.elem.a);
}

dmd a.d
./a

prints:
42
mutable ~this()
123
mutable ~this()

Is it a bug?

I'll wait with a bug report, but I think this should be forbidden.
