In that case, chromatic's code simplifies to
use B::Deparse qw( );
my $deparse = B::Deparse->new();
sub lives_ok(&;$) {
my ($code, $desc) = @_;
$desc = $deparse->coderef2text($code)
if !defined($desc);
return Text::Exception::lives_ok($code, $desc);
}
Be careful to avoid accidently overriding your own functions with those from the module you are extending.

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).
