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: handler.rb
    path of file: ./repos/image_optim/lib/image_optim
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'image_optim/path'
    
    def self.for(original)
      handler = new(original)
      if block_given?
        begin
          yield handler
          handler.result
        ensure
          handler.cleanup
        end
