I think we would be talking about typed variables at that point.
( something you can do with PHP 7.4 http://github.com/azjezz/typed ) even though `as` is used with `foreach`, i don't think it would be an issue to use it for something else, but i think i will leave that to someone who's more familiar with the PHP parser than me.
