code: def with_subsequent_pages
        Enumerator.new { |yielder|
          self.each do |i| yielder << i end
          if has_next_page?
            next_page.with_subsequent_pages.each do |i| yielder << i end
          end
        }
      end
docs: Transparently get all results across all pages. Compare this with #each
   or #results which only iterate over the current page.
  
   Example:
  
     list_response.with_subsequent_pages.each do |result|
       ...
     end
  
   or:
  
     list_response.with_subsequent_pages.count
  
   Pages of results are fetched on demand. When iterating, that means
   fetching pages as results from the current page are exhausted. If you
   invoke a method such as #count, this method will fetch all pages at that
   point. Note that the responses are stored so subsequent pages will not be
   loaded multiple times.
