Perl's %ENV hash is randomized.
First, the order of values returned by hashes isn't random, at least not in any formal sense of the word. There's definitely no attempt to make them random as implied by saying the order is "randomized".
Second, %ENV is magical. It's not really a hash (although it might use one), so the properties of hash don't necessarily apply.
This is just a nit as your point stands without the quoted bit.

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).
