That didn't answer how they can share an address. Suppose I have two 
properties of type QString called "text" and "title".

  action->text = "foo";
  action->title = "bar";

Since std::is_same_v<decltype(action->text), decltype(action->title)> and 
&action->text == &action->title, how does the code above even work?
