<p><b>Discussion:</b></p>

<p><b>Addresses UK 232 [CD1]</b></p>

<p>
<code>match_results</code> may follow the requirements but is not listed a general
purpose library container.
</p>

<p>
Remove reference to <code>match_results</code> against <code>a[n]</code> operation.
</p>

<p><i>[
Summit:
]</i></p>


<blockquote><p>
Agree. <code>operator[]</code> is defined elsewhere.
</p></blockquote>

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

<blockquote><p>
We agree with the proposed resolution.
Move to Tentatively Ready.
</p></blockquote>


<p id="res-1037"><b>Proposed resolution:</b></p>
<p>
In 23.2.4 <a href="https://wg21.link/sequence.reqmts">[sequence.reqmts]</a> Table 84, remove reference to
<code>match_results</code> in the row describing the <code>a[n]</code> operation.
