+      The methods <a href="/pkg/reflect/#Value.Len"><code>Value.Len</code></a> and <a href="/pkg/reflect/#Value.Cap"><code>Value.Cap</code></a> now successfully operate on a pointer to an array and return the length of that array, to match what the <a href="https://go.dev/ref/spec#Length_and_capacity">builtin <code>len</code> and <code>cap</code> functions do</a>.
