It's a bug alright. A documentation bug...
I checked the Unicode properties, and these are the results:
Codepoint | Char | Class |
0024 | $ | Currency Symbol |
002B | + | Math Symbol |
003C | < | Math Symbol |
003D | = | Math Symbol |
003E | > | Math Symbol |
005E | ^ | Modifier Symbol |
0060 | ` | Modifier Symbol |
007C | | | Math Symbol |
007E | ~ | Math Symbol |
So those are not "punctuation" according to the Unicode standard... Time for a PunctPerl class, to keep company to SpacePerl?

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
