Monks, I was toying around with importing/requiring to improve my aptitude with them. So I have this package:

#! /usr/bin/env perl
package A;

require Exporter;
our @ISA = qw(Exporter);
our @EXPORT_OK = qw (sub1 $var);
our %EXPORT_TAGS = (all => [ qw(sub1 $var) ]);

our $var = 7;

sub sub1 {
  print "this\n";
}

1;
[download]

I want to use require to import the $var global. I try this:

#! /usr/bin/env perl

use strict;
use warnings;

use lib '.';
require A;
A->import (':all');

sub1();
print $var . "\n";
[download]

This script throws Global symbol "$var" requires explicit package name (did you forget to declare "my $var"?).

But I have no such error with Use A like so:

#! /usr/bin/env perl

use strict;
use warnings;

use lib '.';
use A ':all';

print $var . "\n";
[download]

So I have a gap in my knowledge. I'm not sure why the second way works and the first doesn't. Any guidance is appreciated. Thanks!
