A lot of people are criticising dynamic typing for this.

It doesn't seem to have anything to do with typing discipline.

    words = (
        'yes',
        'correct',
        'affirmative'
        'agreed',
     )

Would be a tuple (immutable list) of strings, while

    words = (
        'yes',
        'correct',
        'affirmative',
        'agreed',
     )

would also be a tuple of strings.

If haskell had for some reason decided to have the same syntax sugar, it also would have caused an issue.
