| 操作符用來在模式中描述多個接受的模式： > The | operator can be used anywhere within patterns to describe multiple accepted patterns: ~~~ var match = switch(7) { case 4 | 1: "0"; case 6 | 7: "1"; case _: "2"; } trace(match); // 1 ~~~ 在一個 or 模式中，如果有一個捕獲的變量，它必須也出現在它的子模式中。 > If there is a captured variable in an or-pattern, it must appear in both its sub-patterns.
