You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: basic_object.rb
    path of file: ./repos/brew/Library/Homebrew/vendor/bundle-standalone/ruby/2.3.0/gems/backports-3.11.4/lib/backports
    
    the code of the file until where you have to start completion: # Note: Must be required explicitely!
# This is a best attempt to fake BasicObject in Ruby 1.8.x
# What you do get:
#  * as few methods as the real BasicObject (at the moment the library is required...)
#  * BasicObject === <anythi
    
      def inherited(sub)
        BasicObject.class_eval do
          (instance_methods - KEEP).each do |method|
            if Object.method_defined?(method) && instance_method(method).owner == Object.instance_method(method).owner
              undef_method method
            end
          end
        end
