Hi @tomciopp,

Thanks for your pull request.

I had already done this but I was missing the tests, so I used my implementation and refactored your tests to follow our convention.

If you want to contribute in the future, my main recommendation would be that the code should follow the original implementation as closely as possible.

Thanks again!
