My first thought was:
our $flipflop = !1;
our %class = ( $flipflop => 'even', !$flipflop => 'odd' );
sub getclass {
$class{ $flipflop = !$flipflop };
}
The '!' in the initialisation values are to avoid reliance on specific truth values so they can be used safely as hash keys for any given Perl implementation.
update: in practice I'd use an instance variable instead of a class variable for $flipflop, but before that I'd have to do OO makeover of the OP which I avoided doing.

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).
