我猜想是一些Ruby内部元素

class MyClass

  def instance_variable=(var)
    puts \"inside getter\"
    instance_variable = var
  end

  def function_1
    self.instance_variable = \"whatever\"
  end

  def function_2
    @instance_variable = \"whatever\"
  end

end



myclass = MyClass.new

myclass.function1

myclass.function2

instance_variable

self.instance_variable=

def name=(value)
  @name = value
end

attr_reader :name #generates getter only
attr_writer :name #generates setter only, not very common
attr_accessor :name #generates getter and setter

def instance_variable=(var)
  puts \"inside getter\"
  instance_variable = var
end
