===(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。位置仅检查是否存在。

# File prism/node.rb, line 17322
def ===(other)
  other.is_a?(SymbolNode) &&
    (flags === other.flags) &&
    (opening_loc.nil? == other.opening_loc.nil?) &&
    (value_loc.nil? == other.value_loc.nil?) &&
    (closing_loc.nil? == other.closing_loc.nil?) &&
    (unescaped === other.unescaped)
