title: Explicitly deleting a shared_ptr
body: <p>Simple question here: are you allowed to explicitly delete a <code>boost::shared_ptr</code> yourself? Should you ever?</p>
  
  <p>Clarifying, I don't mean delete the pointer held by the <code>shared_ptr</code>. I meant the actual <code>shared_ptr</code> itself. I know most people suggest to not do it, so I was just wondering if it's OK to explicitly do it.</p>
