Subject: Re: iterate chars in a string

each_bytes is not a good way to do this, btw. It will not remain
compatibile with Ruby 2.0. And using enumerator is a pretty heavy
solution. Then there's this...

  require 'facet/string/chars'

Source code for chars.rb:

  class String

    # Returns an array of characters.
    #
    #   "abc".chars  #=> ["a","b","c"]
    #
    def chars
      self.split(//)
    end

  end
