Much fun was spent today tracking down a mysterious bug. I even had fun shoving a coderef into @INC to find out what was loading the errant module. I've now reproduced a minimal test case. Once I put it together, the bug was clear, but before that, there were many red herrings. Here's a minimal test case.
package Package1;
use base 'Exporter';
our @EXPORT_OK = qw/this that/;
our %EXPORT_TAGS = ( all => [qw/this that/], );
sub this { 'this' }
sub that { 'that' }
1;
And another package:
package Package2;
use base 'Exporter';
use Package1 ':all';
our @EXPORT_OK = ( @Package1::EXPORT_OK, 'foobar' );
our %EXPORT_TAGS = %Package1::EXPORT_TAGS;
push @{ $EXPORT_TAGS{all} } => 'foobar';
sub foobar { 'foobar' }
1;
Do you see the bug? That was very, very annoying, but fortunately the fix is easy. If you see the bug, post it as a spoiler.

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).
