How To Install libiterator-perl on Ubuntu 18.04
Introduction

What is libiterator-perl
libiterator-perl is:
Iterator is meant to be the definitive implementation of iterators, as popularized by Mark Jason Dominus’s lectures and recent book (Higher Order Perl, Morgan Kauffman, 2005).
An “iterator” is an object, represented as a code block that generates the “next value” of a sequence, and generally implemented as a closure. When you need a value to operate on, you pull it from the iterator. If it depends on other iterators, it pulls values from them when it needs to. Iterators can be chained together (see Iterator::Util for functions that help you do just that), queueing up work to be done but not actually doing it until a value is needed at the front end of the chain. At that time, one data value is pulled through the chain.
