=== (other)

Source

# File lib/prism/node.rb, line 14705
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?)
end

实现节点的相等性判断。这实际上是 ==，但不比较 location 的值。仅检查 location 是否存在。
