A long time ago, it was a way to carry around filehandles. Perl 5.8 (I think) allowed lexicals to hold filehandles, so this use died out.
Most useful thing I've found is to make a list of simple accessors in a class:
{
my @ACCESSORS = qw{ foo bar baz };
for my $slot (@ACCESSORS) {
no strict 'refs';
*$slot = sub {
my ($self) = @_;
$self->{$slot};
};
}
}
But even this has tended to go away with meta-object systems like Moose (which do similar things under the hood).

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).
