I use modules often. I rarely use a module I don't understand,
though. Hey, it got me to learn a lot about sockets -- I
realized the LWP bundle would do the job of the socket nonsense,
but I wanted to make sure I knew what that nonsense was. If
you think you can make a portable program without using modules,
you're doing one of the following:
- making a program that isn't meant to be ported
- making a simple program that really needn't rely on
complex operations, and therefore complex modules
- making a mistake somewhere
That doesn't mean you can't make something better than a module
that is out there already -- but it's not likely. It is more
than easy to write a crummy CGI query parser that "gets the
job done" when the job consists of reading the query string
from a GET query. But then you might need to add support
for POST, and then come file uploads. And you probably didn't
read the RFC on how query strings can be formatted. It's also
easy to do a crummy job of parsing HTML tags.
If I seem condescending or rude, I apologize, but I've had to
argue my point several times. Not using a module because it's
not in the standard distribution is no excuse -- if a sysadmin
is not competent enough to install a Perl module, then they
don't know how to use gzip, tar, and make. That is very sad.
Or, if they are stingy, and won't do it, you can install the
module in a local directory.
There's a reason there are so many modules. There's a reason
they come with their source and documentation.

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).
