@flacode you did a wonderful job with this PR :D you respected the PR template, you did a squashed commit with an appropriate message and added a test to support your code. I see your commit does not identify your GitHub account, think you can fix that if you want to configure git to know your email with this - https://help.github.com/articles/setting-your-commit-email-address-in-git/ .. in this way you appear on the Contributors page on GitHub repository
