So I guess you'd rather do
my $pointless_reference = $obj->getPosition();
my ($x, $y) = @$pointless_reference[0,1];
or
my ($x, $y) = @{$obj->getPosition()};
instead of
my ($x, $y) = $obj->getPosition();
right? Restricting myself to returning just one value just because most languages do not allow anything more seems silly to me. Especially compared to such dirty tricks as updating the values of some variables passed by reference or something.
To me bending backwards to always return a single scalar is a code smell. A code smell sugesting that the author writes C or some other language, but definitely not Perl. Even though the code is full of sigils and there are regexps scattered around.

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).
