The issue I have isn't so much with the core Perl behavior, so much as the plethora of built-in global variables in Perl, and the general abuse of globals. For example, in one of my @INC directories I ran ack '^\s*\$\w+::.*=' and read plenty of CPAN modules who set global variables for other packages and don't localize those changes. I've had my code break as a result of other people doing that and it's very hard to track down these bugs.
When you combine the potential for mysterious action at a distance along with the relatively inscrutable punctuation variables, it's a double-whammy in my book. Thus, I used to use local $" = ...;, but I've stopped doing that and recommend join (yes, even with array slices) because it's clear and there's less risk of mysterious side effects.

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).
