I am not a fan.
Consider this code:
use HugeObject;
my $result = 0;
{
my $object = HugeObject->new();
$result = $object->get_even_bigger();
$object = undef;
}
# Phew, should free up memory now.
if ($result) {
# code here
}
As the object was created inside the {} it should go out of scope and the memory should be cleared - a good thing. However as object returns a reference to itself it is not cleared, and stays in memory.
If the object had just returned true or false this would not be a problem.
This may not be a problem if you read the docs for HugeObject but why add the compication for some slightly shorter code?
--tidiness is the memory loss of environmental mnemonics

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).

are good places to start.
