>It's so much fun to look at a chain of generic functions working on a generic data structure, while keeping the code clear. Makes me feel all warm inside.

Yeah, that’s usually a bad sign. Programmers who think some language features are “fun” usually end up overapplying them and making life harder for everyone who just want to do their job and ship stuff.

Programming languages should be simple, boring and self-evident.

Keep “fun” in your hobby projects.
