> Now this is starting to look like Professor of Programming Languages code!

A lot of tier 2/3 CS schools with programming language courses (a survey of multiple languages across various paradigms) teach Prolog this way (and I've seen some fantastically terrible examples of Lisp code coming out of those same courses). It's unfortunate because, at these schools, this is often the only formal course where students branch out of C/Java/C++/C#/Python/JS (and they may only get 2-3 of those over the rest of their courses). It leaves the students with a gross misunderstanding of the languages and dread when they see them again.
