Try this one:
#!/usr/bin/perl -w
use strict;
my @k = (1..9);
my $m;
{ local $k[5]="middle";
$m = \@k;
print "@k\n";
my $m = [ 'a'..'z' ];
print "@$m\n";
}
print "@$m\n";
## Returns:
#1 2 3 4 5 middle 7 8 9
#a b c d e f g h i j k l m n o p q r s t u v w x y z
#1 2 3 4 5 6 7 8 9
Pretty ugly, huh?

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.
