IMO the best features of modern Perl are the things that are enabled by default without any special incantations at all -- things like // and named captures, things that actually make it easier to write readable code. In contrast, all say does is save a little typing. Explicit line breaks were never a maintenance problem like defined $8 ? $8 : defined $6 ? $6 : 1.
(I guess given/when might turn out to be totally awesome, but I'm one of those people who never felt the lack of a switch statement in the first place, so I've not got round to trying them yet.)

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).
