unfortunately no, but good idea nonetheless ... :)
DB<39> x @input
0 2

DB<40> use experimental 'refaliasing'; \$input[1] = \$input[-1]
DB<41> x @input
0 2

DB<42> for my $v (@input) { say $v if \$v==\$input[-1] }

I'm not even sure that experimental feature is even needed...
IIRC one could somehow use typeglob aliasing on array elements.

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.
