-w is the same as "use warnings". Warnings turns on
optional warnings that may indicate problems with
your code. Warnings will not stop your program from running,
just send a message when it encounters something.
Warnings also tend to be more run-time messages.
"use strict" restricts the use of unsafe constructs.
Preventing the code from running if you do "dangerous"
things. If something fails the "use strict" test the
program will not run.
strict and warnings are well used together as they
can help you prevent and catch different types of
errors.

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).
