            <title>[SERVER-41130] Add support for bitwise operations on AtomicWord</title>
                <link>https://jira.mongodb.org/browse/SERVER-41130</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;AtomicWord offers a slightly less dangerous, doesn&apos;t require lint, access to std::atomic&apos;s.  &lt;/p&gt;

&lt;p&gt;While that interface currently doesn&apos;t offer access to bit operations, the extra cognitive load to understand those correctly is substantially simpler than the main thing AtomicWord hides (access to non sequential consistency).&lt;/p&gt;

&lt;p&gt;Thus, let&apos;s add bitwise operators for unsigned atomic words&lt;/p&gt;</description>

&lt;p&gt;AtomicWord offers a slightly less dangerous, doesn&apos;t require lint,&lt;br/&gt;
access to std::atomic&apos;s.&lt;/p&gt;

&lt;p&gt;While that interface currently doesn&apos;t offer access to bit operations,&lt;br/&gt;
the extra cognitive load to understand those correctly is substantially&lt;br/&gt;
simpler than the main thing AtomicWord hides (access to non sequential&lt;br/&gt;
consistency).&lt;/p&gt;

&lt;p&gt;Thus, let&apos;s add bitwise operators for unsigned atomic words&lt;br/&gt;
