It is not new, it’s been ages since some developers try to show off by bringing “cool” one liners to solve problems. Stretching operators, bringing up imaginative uses for lambda expressions or kind of abusing parts of the language to make some other teammate or reviewer, What did you make there?

I believe, definitely, that they are quite intelligent people that know a lot about the language or maths, but definitely they are not usually making the smartest choice, because you should use “languages” in order for the people to understand you.

So you can call those: “50 cent expressions”

They help no one but their ego…

In the last times I’ve been seeing lots of “show off” with nitty gritty features of C++… lambdas, templates and inheritance in a pattern that reminds me to the characters in an Agatha Christie book, where you need a graph to keep up with it… Hope this era ends soon.

At least in Haskell, I feel like this doesn't hold true.

Typically more concise code takes advantage of core language abstractions.

It is actually simpler unless you are unfamilar with core language abstractions, but I'd argue that's a you problem.
