===(other) 点击切换源代码

为节点实现 case-equality。这实际上是 ==，但不比较位置的值。仅检查位置是否存在。

# File prism/node.rb, line 11665
def ===(other)
  other.is_a?(LambdaNode) &&
    (locals.length == other.locals.length) &&
    locals.zip(other.locals).all? { |left, right| left === right } &&
    (operator_loc.nil? == other.operator_loc.nil?) &&
    (opening_loc.nil? == other.opening_loc.nil?) &&
    (closing_loc.nil? == other.closing_loc.nil?) &&

    (body === other.body)
