=== (other)

Source

# File lib/prism/node.rb, line 8061
def ===(other)
  other.is_a?(GlobalVariableReadNode) &&
    (name === other.name)
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。

# File lib/prism/node.rb, line 8005
def accept(visitor)
  visitor.visit_global_variable_read_node(self)
end

def accept: (Visitor visitor) -> void
