Subject: confusion with class_eval

class A
end
A.class_eval do
  @@attr = 100
  def self.get_attr
    @@attr
  end
  def self.set_attr(_x)
      p "hi"
    @@attr = _x
  end
end
p A.class_variable_get(:@@attr)
p Object.class_variable_get(:@@attr)

Output:

D:/Rubyscript/My ruby learning days/Scripts/TEST.RB:78: warning: class
variable access from toplevel
100
100

C:\Program Files\Notepad++>

My question is how @attr becomes Object class's class variable?
