数组语法可以用来匹配多个值： > Array syntax can be used to match on multiple values: ~~~ var s = switch [1, false, "foo"] { case [1, false, "bar"]: "0"; case [_, true, _]: "1"; case [_, false, _]: "2"; } trace(s); // 2 ~~~ 这和数组匹配非常相似，但是有以下不同： > This is quite similar to usual array matching, but there are differences: * 元素的量是固定的，所以不接受不同长度的数组 * 不能捕获switch的值到一个变量，如 case x 是不被允许的（case _ 也是）。 > * The number of elements is fixed, so patterns of different array length will not be accepted. > * It is not possible to capture the switch value in a variable,i.e. case x isnotallowed(case _ still is).
