Also, an example like this is very suitable for an Object Oriented application. For example: 
#!/usr/bin/perl
use strict;
use warnings;
my $example = Example->new;
$example->print(
                map { chomp $_;
                      $_;
                    } <STDIN>
                );
$example->print('That\'s all!');

sub Example::new {
    my ($class, $start_num) = @_;
    bless \$start_num, $class;
}

sub Example::print {
    my $self = shift;
    print ++$$self, ": $_\n" for @_;
}
