I can't tell whether this affects you without seeing the rest of your code, but there's a small difference between &foo and foo(). Specifically, &foo will get the current contents of @_ while foo() will not. If Con::liveones is expecting that, then that may be your problem.
bar( qw( testing is fun ) );
sub bar {
&foo;
foo();
&foo();
foo( 'woohoo' );
}
sub foo {
print 'foo: ';
print join q{,}, map { "[$_]" } @_;
print "\n";
}
Outputs:
foo: [testing],[is],[fun]
foo:
foo:
foo: [woohoo]

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).
