I would do it like this. I used "push" to add to the initial array, and I also used UNIVERSAL::require to avoid using eval.

#!/usr/bin/perl -sl

use strict;
use warnings;
require UNIVERSAL::require;

my(@modules) = qw/Test::More Test::HasVersion/;

my $module = $modules[0];
$module->require or die $@;
print $module;

$module = $modules[1];
$module->require or die $@;
print $module;

push(@modules, 'Test::Simple');
$module = $modules[2];
$module->require or die $@;
print $module;

Do this each time you require. Later in the script, you can see what you required by simply calling

print @modules;
