Just a quick note. _ is no longer being used for the concatenation operator, now it's ~.
"hello " ~ "world";
$str ~= "!!!"; # which is different from =~ (if =~ isn't changed)
Also, the "." syntax has one big advantage: topics. When calling a method on the topic ($_ (also $self in OO -- see article on perl.com)), a lone dot looks much better than a lone arrow. .method vs. ->method And it fits my brain better for assignment. elusion : http://matt.diephouse.com

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).
