I agree with everything you've said, and use the operators in the same way myself, with very few exceptions (for example, I might sometimes write if (not ...) instead of unless(...) if it reads better). Consistency is definitely a good thing!
I was just disagreeing with the "never" part - TIMTOWTDI, and function() || ... is valid Perl and sometimes applicable. In the context of the root node, I explicitly included that form because a newcomer might have seen it in other code, and I think it's good to say that it's not wrong, but also not recommended. Anyway, I've edited the root node further to highlight that even more.
(What do you think about if( open($fh, '<', $foo) || open($fh, '<', $bar) )? ;-) )

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).
