With more List::MoreUtils:
use strict;
use warnings;
use Test::More tests => 2;
use List::MoreUtils 'natatime';
my ($C, $R) = (4, 3);
my @list = 1..12;
my @AoA;
my $iter = natatime($C, @list);
while ( my @chunk = $iter->() ) {
push @AoA, [@chunk];
}
is_deeply \@AoA, [[1 .. 4], [5 .. 8], [9 .. 12]];
is_deeply \@list, [1..12];
Updated: fixed two blunders in original post. Thanks LanX.
Update: This question reminds me of another recent node: How to Split on specific occurrence of a comma (where my response contains some CPAN List module refs)

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
