class Object
  class << self

      #-> [:A, #<Class:Object>, [Class, Module, Object, Kernel]]
    alias :_constants :constants
    alias :_instance_methods :instance_methods
    alias :_public_instance_methods :public_instance_methods
    alias :_protected_instance_methods :protected_instance_methods
    alias :_private_instance_methods :private_instance_methods
  end
  p [:B, self, ancestors]  #-> [:B, Object, [Object, Kernel]]
  alias :_methods :methods

klass = String
p klass._constants == klass.constants
