Fun with parentheses

Oh… I almost forgot what fun it is to learn functional programming. During one of the semesters in university, we took “Functional programming” course. It was a new world of something that I hadn’t seen before, so unusual, so charming.
That new world of lists and operations on them was something “weird” because it wasn’t similar [...]
