How To Install liblexical-underscore-perl on Kali Linux

Introduction

In this tutorial we learn how to install liblexical-underscore-perl on Kali Linux.

What is liblexical-underscore-perl

liblexical-underscore-perl is:

Starting with Perl 5.10, it is possible to create a lexical version of the Perl default variable $. Certain Perl constructs like the “given” keyword automatically use a lexical $ rather than the global $_.

It is occasionallly useful for a sub to be able to access its caller’s $_ variable regardless of whether it was lexical or not. The “()” sub prototype is the official way to do so, however there are sometimes disadvantages to this; in particular it can only appear as the final required argument in a prototype, and there is no way of the sub differentiating between an explicitly passed argument and $.

lexical::underscore allows you to access your caller’s lexical $_ variable as easily as:

${lexical::underscore()}
