Exercise "Wordy": README.md doesn't exactly match tests

[antonshevyrin]

In README.md the following is written:

If you'd like, handle exponentials.
> What is 2 raised to the 5th power?

But in wordy.tests.ts:

  xit('too advanced', () => {
    const question = 'What is 53 cubed?'
    const problem  = new WordProblem(question)

    expect(problem.answer.bind(problem)).toThrowError( ArgumentError )
  })

README.md doesn't say anything about implementing unary operations. I understand that handling exponentials is considered as optional but in my opinion it is still a bit confusing when tests are so different from description.

I am not sure I follow. Do you have a proposed solution? Feel free to submit a PR. Thanks for your contribution.

@masters3d
Actually after some investigations I found that this topic was already discussed before: exercism/problem-specifications#738
And it is decided that tests shouldn't cover optional extensions.
This issue must be closed then. Sorry for wrong report!
