For me, it's:
use strict;
use warnings;
no warnings 'once';
because that sodding warning has never caught anything for me that strict wouldn't have trapped sooner. The kicker is that fixing it requires jumping through very silly hoops to make it go away. ( $foo = $foo = 1; anyone?) As for uninitialized - well, I don't get a warning on
if ($foo) { ... }
I admit it's sometimes a little awkward to code around the uninitialized warning, but usually something like adding a || 0 or || '' or such does the trick just fine. And that kind of thing isn't silly, in fact I think it's clearer in intent in that I document via code that I explicitly expect undefs there.

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).
