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: default_sentence.rb
    path of file: ./repos/nlp-pure/lib/nlp_pure/segmenting
    
    the code of the file until where you have to start completion: # encoding: utf-8

module NlpPure
  module Segmenting
    # SEE ALSO: Unsupervised Multilingual Sentence Boundary Detection. Kiss, Strunk; 2006.
    # NOTE: this fails on some proper nouns with abbreviations (e.g. business names)
    #       and fails on single-linebreak headings
    module DefaultSentence
      require_relative './default_utility'
      extend NlpPure::Segmenting::DefaultUti
    
      def next_segment_appears_included?(segment)
        return false unless segment
        # NOTE: the logic is expanded for logging reasons (despite style violation)
        if segment[0] =~ options.fetch(:split, nil)
          STDERR << "\t! leading punctuation detected\n" if ENV['DEBUG']
        elsif segment[0] =~ /^\w/
          STDERR << "\t! assuming abbreviation\n" if ENV['DEBUG']
        elsif segment =~ /^\s[a-z0-9]/
          STDERR << "\t! greedily continuing sentence\n" if ENV['DEBUG']
        elsif segment =~ /^\d/
          STDERR << "\t! leading numeral detected\n" if ENV['DEBUG']
        else
