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: alias.rb
    path of file: ./repos/metasploit-framework/plugins
    
    the code of the file until where you have to start completion: require 'rex/text/table'

module Msf
  class Plugin::Alias < Msf::Plugin
    class AliasCommandDispatcher
      include Msf::Ui::Cons
    
      def deregister_alias(name)
        class_eval do
          # remove the class methods we created when the alias was registered
          remove_method("cmd_#{name}")
          remove_method("cmd_#{name}_tabs")
          remove_method("cmd_#{name}_help")
        end
        # remove the alias from the list of active aliases
        @aliases.delete(name)
      end
