Thinking about 'our' vs 'use vars' made me wonder: Why are you using a var in the first place?
package ConfigThisJunk;
use strict;
use warnings;
use Exporter;
our @ISA = qw( Exporter );
our @EXPORT_OK = qw( DEBUG );
use constant DEBUG => 1;
1;
use strict;
use warnings;
use ConfigThisJunk qw( DEBUG );
my $x = 123;
print("debug: x is $x\n") if DEBUG;
Bonus: If DEBUG is false, the whole print-if is optimised away because it's a constant! (If it's true, the if part is optimised away.)
If you wanted the be able to change DEBUG, this is still cleaner:
package ConfigThisJunk;
use strict;
use warnings;
use Exporter;
our @ISA = qw( Exporter );
our @EXPORT_OK = qw( DEBUG );
my $DEBUG = 1;
sub DEBUG {
if (@_) { $DEBUG = shift; }
return $DEBUG;
}
1;
use strict;
use warnings;
use ConfigThisJunk qw( DEBUG );
my $x = 123;
print("debug: x is $x\n") if DEBUG;

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).
