<a class="reference internal" href="../glossary.html#term-optimized-scope"><span class="xref std std-term">optimized scopes</span></a> is cached on the frame object and will remain
alive as long as the frame object does. Unlike <a class="reference internal" href="#c.PyEval_GetFrameLocals" title="PyEval_GetFrameLocals"><code class="xref c c-func docutils literal notranslate"><span class="pre">PyEval_GetFrameLocals()</span></code></a> and
<a class="reference internal" href="../library/functions.html#locals" title="locals"><code class="xref py py-func docutils literal notranslate"><span class="pre">locals()</span></code></a>, subsequent calls to this function in the same frame will update the
contents of the cached dictionary to reflect changes in the state of the local variables
rather than returning a new snapshot.</p>
