in reply to How to do the follwing in Perl OR any other software

If I understand correctly, I think you want a template for writing new Perl scripts, rather than new Python scripts. Right? If so, I've found from my own experience that a template like the following is far more useful than the pattern shown in the OP.
#!/usr/bin/perl =head1 NAME =head1 SYNOPSIS =head1 DESCRIPTION =head1 AUTHOR {your name and email address here} =cut use strict; use warnings; my $Usage = "Usage: $0 \n";
I delete the $Usage line if I'm writing a module, or when I decide to go with "use Pod::Usage". The NAME, SYNOPSIS and DESCRIPTION sections always get filled in before I write any of the code. (There's probably a nifty way to have the NAME section initialized to the name of the file being edited -- that's an itch to be scratched...)

I know there's a way in emacs to have a template file loaded into the editing buffer every time you start a new file with a given extension (e.g. *.pl or *.pm), but I'm content just to have the above template stored in an easy-to-find file, and do "meta-x include-file" every time I start a perl script.
