I use this recipe in most scripts:
use Getopt::Long;
sub pod2usage { require Pod::Usage; goto \&Pod::Usage::pod2usage; }
GetOptions(
...
...
) or pod2usage(2);
I don't mind paying for Getopt::Long because I like its features, but there's no reason to load Pod::Usage unless the user screws up the commandline.
On that note, someone ought to contribute a patch to Pod::Usage that avoids loading anything until it gets called. Then I could skip that bit of ugly boilerplate in my code.

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).
