Thanks, and yes, good points! The node is aimed at people using the open statement in a "non-best-practice" way, so I'd like to keep the node short enough so that they might still read it (hence all the bold text and TL;DR at the top), and I'd like to keep the focus on the open statement itself - I left out a discussion e.g. of piped opens and checking close for errors and such intentionally, because when answering questions about that, I have other nodes I'd link to instead. Perhaps your reply to my node pointing these things out is enough? :-)
Update: Ok, I've updated the root node!

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).

or How to display code and escape characters
are good places to start.
