I would look at the problem from another side ;-)
#!perl
use strict;
use warnings;
local $, = "\n";
local $\ = "\n";
my @a = (1..5);
foreach (reverse @a){
$a = pop @a;
print "Deleted value: $a";
}
print "\nDeleted Array Content: ", @a;
__DATA__
Deleted value: 5
Deleted value: 4
Deleted value: 3
Deleted value: 2
Deleted value: 1
Deleted Array Content:
Working backwards and pop-ing, I don't change index of the remaining items in the array.
The deletion could even be conditional using splice as in:
#!perl
use strict;
use warnings;
local $, = "\n";
local $\ = "\n";
my @a = (0..5);
foreach (reverse @a){
next unless $_ % 2;
splice(@a, $_, 1);
print "Deleted value: $_";
}
print "\nDeleted Array Content: ", @a;
__DATA__
Deleted value: 5
Deleted value: 3
Deleted value: 1
Deleted Array Content:

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.
