+ * Wire that is capable of upgrading itself upon an 101 status code.
+ * @since 0.1
+ * @todo #23:30 min As discovered in #53, the upgrade is not a job of the
+ *  wire because it need reading the contents of the response (in this case,
+ *  status code). So, this feature would be under the responsibility of a
+ *  response-like object. It must be implemented someway like this:
+ *  new HtUpgradedResponse(
+ *  new IterableOf<>(
+ *  new MapEntry<Func<String, Boolean>, Func<URI, Wire>>(
+ *  upgrade -> upgrade.contains("TLS"),
+ *  HtSecureWire::new
+ *  )
+ *  )
+ *  )
+ *  The test HtUpgradeWireTest#testHtUpgrade must be removed after the
+ *  implementation of this class.
