So, must I repeat the entire subroutine in the code, changing only its name? or is there a way to alias it to another name?

There are two methods to acheive this without duplication of the code inside the subroutine. viz:

#!/usr/bin/env perl
use strict;
use warnings;

sub hello { print "Hello $_[0]!\n"; }

*hi = \&hello;

sub bonjour { &hello }

hello ('there');
hi ('world');
bonjour ('Alain');

It's usually cleaner and clearer just to have the one name for any given piece of functionality, however.
