===(other) 点击切换源代码

为节点实现 case 相等性。这实际上是 ==，但不比较位置的值。位置仅检查是否存在。

# File prism/node.rb, line 8999
def ===(other)
  other.is_a?(InNode) &&
    (pattern === other.pattern) &&
    (statements === other.statements) &&
    (in_loc.nil? == other.in_loc.nil?) &&
    (then_loc.nil? == other.then_loc.nil?)
end
