Iterators with a capital I are not functional.

Functions like ‘map’, and ‘fold’, and ‘zip’ are; but Iterator is not the term to describe such function.

Truth be told, me writing Iterators with a capital I comes from when I finally had this "click in my mind" moment where I got to see clearly how map & friends work, by using Rust [1] to solve a bunch of Advent of Code 2019 problems
