@OmarUsman hey, thanks for the PR. I like the idea behind this, the approach is elegant.

In order for this to be merged, make sure you can check the boxes in the PR template (i added them back in to the description.). Tests, Docs and the Changelog should be in place.

In addition to the @rules directive, the @rulesForArray directive should also receive an update.
