How To Install liblexical-underscore-perl on Debian 11
Introduction
In this tutorial we learn how to install liblexical-underscore-perl
on Debian 11.
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()}
