<p>observable and assignable proxy to concrete value </p>
<p>Observers can be registered with instances of this class so that they are notified when a different value is assigned to such instances. Client code can copy the contained value or pass it to functions via implicit conversion. </p><dl class="section note"><dt>Note</dt><dd>it is not possible to call non-const method on the returned value. This is by design, as this possibility would necessarily bypass the notification code; client code should modify the value via re-assignment instead. </dd></dl>
