sub func {
my ( $rs_str, $hr_desktop_info, $ha_files ) = @_;
$$str = update_string_ref();
for ( keys %$desktop_info ) {
...
push @$files, $file;
}
....
}
I rather feel that $$str, %$desktop_info and @$files
make it pretty clear, not only that your dealing with references,
but also what type of references they are.
If you're having problems reading that, I suggest you do what ++stevieb
has already alluded to and put the prefixes in a comment.
Something like:
my ($str, $desktop_info, $files) = @_; # rs, rh, ra
Update (minor typo fix): s{deck}{desk} in ..., %$decktop_info and ....

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).
