All,
Here is an idea I came up with in #perl (freenode) thanks to a few folks there. Assume an even number of elements:
- 1. Shuffle the indices of the array (copy not actual values)
- 2. Swap adjacent pairs (actually change values)
For instance: 0 - 9 might become 5, 3, 1, 2, 4, 7, 9, 8, 0, 6
Swap index 5 with 3, 1 with 2, 4 with 7, and 9 with 8

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).
