When I first came to Perl, I was annoyed by the sigils because I would always forget to use them when naming variables. However, I quickly came to understand how very useful it is to be able to identify the sort of value you're looking at in a glance. The only similar method is the so-called Hungarian notation, which is unwieldy and ugly (IMNSHO, anyway). Now I wonder how I ever got along without the sigils. They make coding and debugging so much simpler.

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).
