    * Falls nicht, sieht der Client einen hilfreichen, klaren Fehler.
* Prüfen, ob es einen optionalen Query-Parameter namens `q` (wie in `http://127.0.0.1:8000/items/foo?q=somequery`) für `GET`-Requests gibt.
    * Da der `q`-Parameter mit `= None` deklariert ist, ist er optional.
    * Ohne das `None` wäre er erforderlich (wie der Body im Fall von `PUT`).

   *   Iterator<E> it = set.iterator();
   *   while (it.hasNext()) {
   *     foo(it.next());
   *   }
   * }
   * }
   *
   * <p>or:
   *
   * {@snippet :
   * NavigableSet<E> set = synchronizedNavigableSet(new TreeSet<E>());
   * NavigableSet<E> set2 = set.descendingSet().headSet(foo);
   * ...
   * synchronized (set) { // Note: set, not set2!!!

   * ...
   * synchronized (table) { // Synchronizing on table, not row!
   *   Iterator<Entry<C, V>> i = row.entrySet().iterator(); // Must be in synchronized block
   *   while (i.hasNext()) {
   *     foo(i.next());
   *   }
   * }
   * }
   *
   * <p>Failure to follow this advice may result in non-deterministic behavior.
   *
   * <p>The returned table will be serializable if the specified table is serializable.

* Validará que el `item_id` sea del tipo `int` para requests `GET` y `PUT`.
    * Si no lo es, el cliente verá un error útil y claro.
* Revisa si hay un parámetro de query opcional llamado `q` (como en `http://127.0.0.1:8000/items/foo?q=somequery`) para requests `GET`.
    * Como el parámetro `q` está declarado con `= None`, es opcional.
    * Sin el `None` sería requerido (como lo es el body en el caso con `PUT`).

* Validar que `item_id` é do tipo `int` para requisições `GET` e `PUT`.
    * Se não for, o cliente verá um erro útil e claro.
* Verificar se existe um parâmetro query opcional nomeado como `q` (como em `http://127.0.0.1:8000/items/foo?q=somequery`) para requisições `GET`.
    * Como o parâmetro `q` é declarado com `= None`, ele é opcional.
    * Sem o `None` ele seria obrigatório (como o corpo no caso de `PUT`).

そうすると、デフォルト値はレスポンスに含まれず、実際に設定された値のみが含まれます。

そのため、ID `foo` のitemに対してその *path operation* へリクエストを送ると、レスポンスは以下のようになります（デフォルト値を含まない）:

```JSON
{
    "name": "Foo",
    "price": 50.2
}
```

fmt.Println(s1, s2)            // prints [42] [42 2 3]

var m1 = make(map[string]int)
var m2 = m1                    // m2 stores the map descriptor of m1
m1["foo"] = 42                 // setting m1["foo"] changes m2["foo"] as well
fmt.Println(m2["foo"])         // prints 42
