void messwith(T)(ref const(T)[] ts, const(T) t) {
    ts ~= t;
}

class C {
    int x;
    this(int i) { x = i; }
}

void main(string[] args) {

    C[] cs;
    immutable C ci = new immutable(C)(6);

    assert (ci.x == 6);

    messwith(cs,ci);

    cs[$-1].x = 14;

    assert (ci.x == 14); //whoops.
}

I'm pretty sure you shouldn't be able to do that.
