de>: <code>Pointer&lt;T&gt;</code> must, informally speaking, mimic <code>T*</code>; formally being a <em>fancy pointer</em> in the STL sense. The locally-dereferenceable <code>T*</code> it yields must point to the same underlying area in SHM regardless of in which <code>Arena</code>-aware process the deref API is invoked.<ul>
<li>The <code>class</code> keyword is for exposition only; it can also be <code>using</code>, <code>typedef</code>, or anything else, provided it mimics <code>T*</code> as described.<
