+      The new
+      <a href="/pkg/reflect/#Value.CanConvert"><code>Value.CanConvert</code></a>
+      method reports whether a value can be converted to a type.
+      This may be used to avoid a panic when converting a slice to an
+      array pointer type if the slice is too short.
+      Previously it was sufficient to use
+      <a href="/pkg/reflect/#Type.ConvertibleTo"><code>Type.ConvertibleTo</code></a>
+      for this, but the newly permitted conversion from slice to array
+      pointer type can panic even if the types are convertible.
