===(other) 点击以切换源代码

为节点实现大小写相等。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 14019
def ===(other)
  other.is_a?(OptionalParameterNode) &&
    (flags === other.flags) &&
    (name === other.name) &&
    (name_loc.nil? == other.name_loc.nil?) &&
    (operator_loc.nil? == other.operator_loc.nil?) &&
    (value === other.value)
end
