* {@code asMap} has a few subtleties. As long as the set of keys remains unchanged, adding or
 * removing mappings does not affect the key iteration order. However, if you remove all values
 * associated with a key and then add the key back to the multimap, that key will come last in the
 * key iteration order.
 *
 * <p>The multimap does not store duplicate key-value pairs. Adding a new key-value pair equal to an
 * existing key-value pair has no effect.

這表示 `item` 可以是 `int` 或 `str`。

#### 可能為 `None` { #possibly-none }

你可以宣告某個值可以是某個型別（例如 `str`），但它也可能是 `None`。

使用 `str | None` 而不是單純的 `str`，可以讓編輯器幫你偵測錯誤，例如你以為某個值一定是 `str`，但它其實也可能是 `None`。

### 類別作為型別 { #classes-as-types }

你也可以用類別來宣告變數的型別。
