I'm surprised nobody has mentioned it yet, but this is one of the aspects or programming that Objects have come to solve. Namely, this is solved by encapsulation. That's when you hide your data (those pesky global variables) inside the object, and then you attach methods to the object to handle the data, and it all happens in a nice, self-contained (encapsulated, you might say) way.
It's not hard to write your own little module implementing a class which wraps up the global variables and their associated methods. See perltoot for more info.

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).
