Do you perhaps want fast lookups of the prices?
Yes, exactly. This actually a rewrite of another script. The orginal programmer used a long series of if/elsif statements. This is how I cleaned it up.
This way, there's no need to store two versions of the key.
The real problem comes like this:
use CGI qw(:standard);
my $input_item = param('item') || 0;
my $subtotal;
my $item_name;
if(exists $ITEMS{$input_item}) {
$subtotal = $input_item;
$item_name = $ITEMS{$input_item};
}
---- I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.

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).
