===(other) 点击以切换源代码

实现节点的 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 14497
def ===(other)
  other.is_a?(PinnedExpressionNode) &&
    (expression === other.expression) &&
    (operator_loc.nil? == other.operator_loc.nil?) &&
    (lparen_loc.nil? == other.lparen_loc.nil?) &&
    (rparen_loc.nil? == other.rparen_loc.nil?)
