title: shared_ptr vs scoped_ptr
body: <p><code>scoped_ptr</code> is not copy able and is being deleted out of the scope. So it is kind of restricted <code>shared_ptr</code>. So seems besides the cases when you really need to restrict the copy operation <code>shared_ptr</code> is better to use. Because sometimes you don’t know you need to create a copy of your object or no. So the question is: besides the cases mentioned above, could we consider that <code>shared_ptr</code> is better (or recommended) to use instead of <code>scoped_ptr</code>. Does <code>scoped_ptr</code> work much faster from <code>shared_ptr</code>, or does it have any advantages?</p>
