<code>class directory_entry</code> should retain <code>operator const path&amp;()</code> from V2.
</p>

  <p><i>[2014-05-19 Beman Dawes supplied proposed wording.]</i></p>

  <p><i>[2014-06-02 Beman Dawes provides rationale:]</i></p>

  <blockquote>
    This conversion operator was removed when <code>status()</code> and <code>symlink_status()</code>
    were added during the transition from V2 to V3 as it seemed a bit unusual to have a conversion
    operator for one of the several values held. Users complained as they had found the
    automatic conversion convenient in the most common <code>directory_entry</code> use case.
  </blockquote>
  <p><i>[17 Jun 2014 Rapperswil LWG discusses in depth, accepts proposed wording.]</i></p>
  


<p id="res-2640"><b>Proposed resolution:</b></p>
  <p>
    <i>Change 12 Class directory_entry [class.directory_entry]:</i>
  </p>
  <blockquote>
    <pre>// observers
const path&amp;  path() const noexcept;
<ins>operator const path&amp;() const noexcept;</ins>
file_status  status() const;
file_status  status(error_code&amp; ec) const noexcept;
file_status  symlink_status() const;
file_status  symlink_status(error_code&amp; ec) const noexcept;</pre>
  </blockquote>

  <p>
    <i>Change 12.3 directory_entry observers [directory_entry.obs]:</i>
  </p>
  <blockquote>
    <pre>const path&amp; path() const noexcept;
<ins>operator const path&amp;() const noexcept;</ins></pre>
    <blockquote>
      <p>
        <i>Returns:</i>
        <code>m_path</code>
