No one would ever see any of my code having this kind of indent, so I can't see what you're talking about if you can't at least stay on topic. Open '{' on the end, close '}' on the beginning.
Unless and wantarray when done well are good.
Moose at CPAN looks promising and shows how to be more fun than one should have. The difference between hash enumerated, set to true, reverse hash (careful keys), etc.
is to be considered, I think.
Names are variables and variables names.
if($i == $$ar_l $i && $hr_h->{$i} == $this)
# not my indent type :-)
{
....
push(@these, $ar_l-> $i);
}
}

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.
