+<p>
+  Go 1.21 adds two new built-ins to the language:
+  the new functions <code>min</code> and <code>max</code> compute the
+  smallest (or largest, for <code>max</code>) value of a fixed number
+  of given arguments.
+  See the language spec for <a href="https://tip.golang.org/ref/spec#Min_and_max">details</a>.
