<p><b>Discussion:</b></p>
<p>
24.5.4 <a href="https://wg21.link/move.iterators">[move.iterators]</a> has an incorrect example:
</p>

<blockquote>
<p>
-2- [<i>Example:</i>
</p>

<blockquote><pre>
set&lt;string&gt; s; 
// populate the set s 
vector&lt;string&gt; v1(s.begin(), s.end());          // copies strings into v1 
vector&lt;string&gt; v2(make_move_iterator(s.begin()), 
                  make_move_iterator(s.end())); // moves strings into v2
</pre></blockquote>

<p>
<i>-- end example</i>]
</p>
</blockquote>

<p>
One can not move from a <code>set</code> because the iterators return <code>const</code>
references.
</p>

<p><i>[
Batavia (2009-05):
]</i></p>

<blockquote><p>
We agree with the proposed resolution. Move to NAD Editorial.
</p></blockquote>



<p id="res-979"><b>Proposed resolution:</b></p>
<p>
Change 24.5.4 <a href="https://wg21.link/move.iterators">[move.iterators]</a>/2:
</p>

<blockquote>
<p>
-2- [<i>Example:</i>
</p>

<blockquote><pre>
<del>set</del><ins>list</ins>&lt;string&gt; s; 
// populate the <del>set</del><ins>list</ins> s 
vector&lt;string&gt; v1(s.begin(), s.end());          // copies strings into v1 
vector&lt;string&gt; v2(make_move_iterator(s.begin()), 
                  make_move_iterator(s.end())); // moves strings into v2
</pre></blockquote>

<p>
<i>-- end example</i>]
