Looks a little weird, but, doesn't this solve your problem?
use strict;
use warnings;
package Foo::Bar;
sub new {
tie my @arr, 'Foo::Bar';
return bless \@arr, 'Foo::Bar';
}
sub lalala {
my $self = shift;
print "Lalala\n";
}
sub TIEARRAY {
return bless [], 'Foo::Bar';
}
sub FETCH {
print "Fetch\n";
my ($self, $index) = @_;
return $self->[$index];
}
sub STORE {
print "Store\n";
my ($self, $index, $value) = @_;
return $self->[$index] = $value;
}
package main;
my $a = Foo::Bar->new();
$a->lalala();
$a->[0] = 1;
print $a->[0];

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.
