There is a 0% chance that the vast majority of this site and the repo that was linked elsewhere was written by a human. I would have zero confidence in anything about this language, and frankly your former colleague should be embarrassed about putting this out.

Edit: I just noticed in another comment: "Perfect for : Trading systems, industrial control, Medical devices, aerospace applications". I'd go further than embarrassed, and say this person should be ashamed of themself and take this down.
