There are multiple ways to do so, here are three:
$ cat u.pl
use strict;
use warnings;
use Data::Dumper;
my @AoA = (
[ "fred", "barney" ],
[ "george", "jane", "elroy" ],
[ "homer", "marge", "bart" ],
);
# Add to beginning of array
unshift @AoA, [ "pebbles", "bamm bamm", "dino" ];
# Splice into beginning of array
splice @AoA, 0, 0, [ "Fred", "Velma", "Shaggy", "Scooby" ];
# Rebuild with new entry at beginning
@AoA = ( [ "Bugs", "Daffy" ], @AoA );
print Dumper(\@AoA);
$ perl u.pl
$VAR1 = [
[
'Bugs',
'Daffy'
],
[
'Fred',
'Velma',
'Shaggy',
'Scooby'
],
[
'pebbles',
'bamm bamm',
'dino'
],
[
'fred',
'barney'
],
[
'george',
'jane',
'elroy'
],
[
'homer',
'marge',
'bart'
]
];

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).
