<p>
<code>directory_iterator</code> and <code>recursive_directory_iterator</code> are constant iterators, but their
<code>pointer</code>/<code>reference</code> typedefs are wrong (<code>std::iterator</code> defaults to providing modifiable
ones).</p>

<p><i>[2014-02-08 Daniel comments]</i></p>

<p>
I noticed the same problem when trying to resolve <a href="lwg-defects.html#2652" title="[filesys.ts] [PDTS] Better to avoid deriving from std::iterator (Status: TS)">2652</a><sup><a href="https://cplusplus.github.io/LWG/issue2652" title="Latest snapshot">(i)</a></sup>. The currently suggested wording for that
issue should fix the here mentioned problem as well.
<p/>
I recommend to solve this issue as "Resolved by the proposed wording for <a href="lwg-defects.html#2652" title="[filesys.ts] [PDTS] Better to avoid deriving from std::iterator (Status: TS)">2652</a><sup><a href="https://cplusplus.github.io/LWG/issue2652" title="Latest snapshot">(i)</a></sup>".
