If your cases don't need to be evaluated conditionally, I like to use a hashref:
my $dispatch = {
option1 => sub { print "opt 1\n"},
option2 => sub { print "opt 2\n"},
option3 => sub { print "opt 3\n"},
default => sub { print "default\n" },
};
$dispatch->{($dispatch->{$option})?$option:'default'}->(@args);
YMMV,

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).

or How to display code and escape characters
are good places to start.
