class Prism::MultiWriteNode
表示对多目标表达式的写入。
a, b, c = 1, 2, 3 ^^^^^^^^^^^^^^^^^
属性
表示 splat 节点之前的目标表达式。
a, b, * = 1, 2, 3, 4, 5 ^^^^
splat 节点可以不存在,在这种情况下,所有目标表达式都在 left 字段中。
a, b, c = 1, 2, 3, 4, 5 ^^^^^^^
表示目标表达式中的 splat 节点。
a, b, *c = 1, 2, 3, 4
^^
variable 可以为空,这将导致一个带有 nil 表达式字段的 SplatNode。
a, b, * = 1, 2, 3, 4
^
如果省略了 *,此字段将包含一个 ImplicitRestNode
a, b, = 1, 2, 3, 4
^
表示 splat 节点之后的目标表达式。
a, *, b, c = 1, 2, 3, 4, 5
^^^^

实现节点的相等性判断。这实际上是 ==,但不比较 location 的值。仅检查 location 是否存在。
