Can't see internal variable in epic - eclipse

Question

I have installed epic in eclipse for debugging perl. at first I couldn't see any variable while debugging. I found that I need to install PadWalker. That partially solved the problem because I could see all variable BUT I was missing Internal Variables (like @ARGV). Any advise ? using centOS 6, eclipse Version: Kepler Service Release 1 Build id: 20130919-0819 and epic

All variables in the local scope can bee seen from the %main:: namespace:

use Data::Dumper;

my @val;
my @names;
for my $name (keys %main::){

    my $glob = $main::{$name};
    if (defined ${$glob}) {
        push @names, '$' . $name;
        push @val, ${$glob};
    }

    if (defined @{$glob}) {
        push @names, '@' . $name;
        push @val, [@{$glob}];
    }

    if (defined %{$glob}) {
        push @names, '%' . $name;
        push @val, {%{$glob}};
    }
}
my $d = Data::Dumper->new(\@val, \@names);
print STDERR $d->Dump

The output will be like this:

$@ARGV = [
           'aaa',
           'bbb',
           'ccc'
         ];
