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: mongo_base.rb
    path of file: ./repos/geocoder/lib/geocoder/stores
    
    the code of the file until where you have to start completion: module Geocoder::Store
  module MongoBase

    def self.included_by_model(base)
      base.class_eval do

      
    
    def reverse_geocode
      do_lookup(true) do |o,rs|
        if r = rs.first
          unless r.address.nil?
            o.__send__ "#{self.class.geocoder_options[:fetched_address]}=", r.address
          end
          r.address
        end
