I agree entirely, and just wanted to add: a common misconception (one that I was guilty of myself sometimes, before being enlightened about it) is that a regex that doesn't start with ^ but ends with $ somehow changes the behavior of the regex engine to start looking at the end of the string - this isn't how it works, the regex engine always matches from left to right and stops at the first match it finds. A regex of "/foo/bar/baz" =~ m{/[^/]+$} will still cause the regex engine to attempt to match /foo and /bar before settling on /baz - you can see this in action at this link (JavaScript and a modern browser required) when you click the use re "debug"; button.
Update: Corrected = to =~, thanks hippo!

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).
