Sorry for not coming up with this ugly solution while you were asking about it in the CB:
#!/usr/bin/perl -w
use strict;
sub alias{ \@_ };
my @a = (1,"world");
my $arr = alias( $a[0], $a[0], $a[1] );
$arr->[0] = "hello";
print "@$arr\n";
I learned this ugly trick from demerphq while he was testing the aliasing features of his DDS module, so maybe looking at what the dumpers and their tests do might give you some more inspiration.
Updated: Fixed typo in sub alias, spotted by nothingmuch
Updated: I use strict; but the code won't run like that. That should teach me about posting when I don't cut'n'paste my code ... Spotted by The Mad Hatter

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
