C/AL is a product of Microsoft and is only used in their ERP Software Navision. It's a horrible experience to work with as you don't have a lot of modern languages features just for the sake of readability.
At some point in the article the author wrote that Rust code isn't readable for example. I'd argue code shouldn't have to be readable by non-programmers. And especially not if the language sacrifices features like creating objects or dynamic arrays...
But as I wrote, I don't have actual experience with Pascal so maybe it's actually better.
