<p>
LWG <a href="lwg-defects.html#2194" title="Impossible container requirements for adaptor types (Status: C++14)">2194</a><sup><a href="https://cplusplus.github.io/LWG/issue2194" title="Latest snapshot">(i)</a></sup> removed "These container adaptors meet the requirements for sequence containers." from 
23.6.1 <a href="https://wg21.link/container.adaptors.general">[container.adaptors.general]</a>.
<p/>
However, N3936 23.3.1 <a href="https://wg21.link/sequences.general">[sequences.general]</a>/p2 still says "The headers <code>&lt;queue&gt;</code> and <code>&lt;stack&gt;</code> 
define container adaptors (23.6) that also meet the requirements for sequence containers." I assume this is just an oversight.

<p id="res-2427"><b>Proposed resolution:</b></p>
<ol>
<li><p>Delete paragraph 2 of 23.3.1 <a href="https://wg21.link/sequences.general">[sequences.general]</a> as indicated:</p>

<blockquote>
<p>
<del>-2- The headers <code>&lt;queue&gt;</code> and <code>&lt;stack&gt;</code> define container adaptors (23.6) that 
also meet the requirements for sequence containers.</del>
</p>
</blockquote>
