this isn't something you should use recursion for
s/should/need to/
You also don’t need a module. Here is a solution using a stateful subroutine as an iterator:
#! perl
use strict;
use warnings;
my @list = ('a' .. 'z');
my $size = 5;
_array_chunk_it($size, @list);
while (my @chunk = _array_chunk_it())
{
print "Array chunk of $size =\n", join("\n", @chunk), "\n\n";
}
{
my ($array, $count);
sub _array_chunk_it
{
my @chunk;
if (@_)
{
$count = shift;
$array = [ @_ ];
}
else
{
for (1 .. $count)
{
push(@chunk, shift @$array) if @$array;
}
}
return @chunk;
}
}
(With newer versions of Perl, this can be rewritten using state.)

Are you posting in the right place? Check out Where do I post X? to know for sure.

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.
