For a lighter solution, just use a (built-in) dualvar:
use Scalar::Util 'dualvar';
my $funny = dualvar 12, 'pancake';
printf "Polly wanna %s every %d days \n", $funny, $funny;
printf "Polly wanna %s every %d days \n", $funny, 0+$funny;
__END__
Or, if you really do want a full object-based solution,
Contextual::Return can do the hard work (of setting up the class and overloading) for you:
use Contextual::Return;
my $funny = NUM { 12 }
STR { 'pancake' };
printf "Polly wanna %s every %d days \n", $funny, $funny;
printf "Polly wanna %s every %d days \n", $funny, 0+$funny;
__END__
But, if you just want number and string, a dualvar is probably the better choice.

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).
