struct S {
    @disable this();

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

    void foo() {
        assert(cted);
    }
}

void bar(A a) {
    a.s.foo();   
}

class A {
    S s;
    this() {
        bar(this); // shouldn't compile
        s = S(1);
    }
}

void main() {
    auto a = new A;
}

Passing 'this' outside the constructor should be disallowed before structs with disabled constructors are initialized.

I could go on with bug reports but it is obvious that there is no good solution  in the face of current compilation model.
