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;
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 $var . "\n";
This script throws Global symbol "$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";
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!

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
