This illustrates what I meant in bug 10186, comment 6:

struct S {
    @disable this(); 

    bool cted;
    this(int x) {
        cted = true;
    }

    static int destroyedBeforeConstructed;
    ~this() {
        if (!cted)
            destroyedBeforeConstructed++;
    }
}

class A {
    S s;

    this() {
        s = S(1);
    }
}

void main() {
    auto a = new A;
    assert(S.destroyedBeforeConstructed == 0);
}

Assertion fails because assignment triggers destruction of a struct that has
never been constructed.

With this one, object lifetime management remains fatally broken.
