Just for the fun of it...
package base1arrays;
use strict;
use warnings;
sub TIEARRAY {
my ($pack,$arr) = @_;
bless $arr, $pack;
}
sub FETCH {
my ($arr,$i) = @_;
return $arr->[$i-1];
}
sub FETCHSIZE {
@{$_[0]};
}
sub STORE {
my ($arr,$i,$v) = @_;
$arr->[$i-1] = $v;
return;
}
1;
Test:
use strict;
use warnings;
use feature qw/ :5.10 /;
use base1arrays;
my @orig = qw/1 2 3 4 5/;
tie my @arr, 'base1arrays',\@orig or die $!;
say for (1..@arr);
# "negative" (< 1) index also works
say $arr[0]; # Prints 5

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.
