Subject: array.include?  I do not seem to GET it

I have this set of constructs:

  def initialize(argv)
    @argv = argv
  end

  def start
      puts @argv.class
      puts @argv.size
      puts @argv
      @argv.include?('--update') ? puts("Includes update") : puts("No
--update")
   ...

which produces this output for a given input:

Array
4
'-s /doc/data/fx-noon-all-2009-04-15.xml'
'-f csv'
'-o forex_testing'
'--update'
'-t'
No --update

Now. Here are the posers that I cannot answer.

Why is #size == 4 rather than 5; and

Why is '--update' listed when printing the array but it is not found in
the same array by #include?('--update'). What is it that I am getting
wrong here?
