And now I have fixed the class so that it now works when you rank a
language whose name doesn't end with plus sign ... and I assume that
giving a rank of zero to a language means that it's the ultimate.

  class Howard
    class TooPainFulError < StandardError; end
   
    def initialize
      @langs = %w(ruby c perl java idl bash sh zsh tcsh csh fortran c++)
    end

    def rank lang
      ## Incorrect line replaced:
      ## raise NotImplementedError, lang unless @langs.index lang
      raise NotImplementedError, lang unless (i = @langs.index lang)
   
      case lang
        when /[^+]$/
          puts "#{lang} is my ##{i} ranked language"
        else
          raise TooPainFulError, lang
      end
    end
  end

  ara = Howard.new
  ara.rank "c++" 
  ara.rank "c" 
  ara.rank "ruby"
