//@ Rust provides a whole lot of methods on iterators that allow us to write pretty functional-style list manipulation.
// Let's say we want to write a function that increments every entry of a `Vec` by some number, then looks for numbers larger than some threshold, and prints them.

//@ `map` takes a closure that is applied to every element of the iterator. `filter` removes elements
//@ from the iterator that do not pass the test given by the closure.
