The 'ref' by 'getA' is ignored.

[code]
import std.stdio;

struct A {
public:
    int id;

    this(int id) {
        writeln("CTor ", id);

        this.id = id;
    }

    this(this) {
        writeln("Postblit ", this.id);

        this.id *= 2;
    }

    ~this() {
        writeln("DTor ", this.id);
    }
}

class B {
private:
    A _a;

public:
    this() {
        this._a = A(42);
    }

    ref A getA() {
        writeln("Return A");
        return this._a;
    }
}

void main() {
    B b = new B();
    A a = b.getA();
}
[/code]

Expected Output:
----
CTor 42
DTor 0
Return A
DTor 42
----

Current Output:
----
CTor 42
DTor 0
Return A
Postblit 42
DTor 84
DTor 42
----
