            <title>[SERVER-84849] POC: New positional path syntax in agg: &quot;a.$[0]&quot;</title>
                <link>https://jira.mongodb.org/browse/SERVER-84849</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;At a first guess, there are three main pieces to this work: &lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;Adding logic to the FieldPath class to notice and accept something like &quot;$&lt;span class=&quot;error&quot;&gt;&amp;#91;0&amp;#93;&lt;/span&gt;&quot;.&lt;/li&gt;
	&lt;li&gt;Adding logic to the Document and Value classes to interpret this correctly in methods like &apos;getDottedPath&apos;&lt;/li&gt;
	&lt;li&gt;Adding logic to the $project and $addFields stages to support something like {$addFields: {&quot;a.$&lt;span class=&quot;error&quot;&gt;&amp;#91;0&amp;#93;&lt;/span&gt;&quot;: 1}} - $project might be slightly weirder with its semantics of how anything not referenced is not included.&lt;/li&gt;
&lt;/ol&gt;
