Below is an excerpt from the book "Effective Perl Programming" by Joseph N. Hall and our friend merlyn. It is taken from the first paragraph of chapter 3:
Perl is a language designed by a linguist, and as much as any human lan-guage,
Perl is a language of idioms.
What I call idiomatic Perl is the mixture of elegance and custom that
comes naturally to Perl programmers, or, at least hopefully, to the majority
of them, after experience and experimentation. Exactly what is idiomatic
and what is purely a matter of style or opinion is debatable. There are
many different ways to express both simple and complex algorithms in
Perl. Some ways, however, are clearly more “right” than others.

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).
