You could use an on-the-fly subroutine. Probably not a good approach if the arrays are large.
johngg@abouriou:~$ perl -Mstrict -Mwarnings -MData::Dumper -E '
my @list = qw{ 1 2 3 4 5 6 7 8 9 10 11 12 };
my( $nCols, $nRows ) = ( 4, 3 );
my @AoA = sub {
my @tAoA;
push @tAoA, [ splice @_, 0, $nCols ]
while @_;
return @tAoA;
}->( @list );
print Data::Dumper->Dumpxs( [ \ @list, \ @AoA ], [ qw{ *list *AoA } ]
+);'
@list = (
'1',
'2',
'3',
'4',
'5',
'6',
'7',
'8',
'9',
'10',
'11',
'12'
);
@AoA = (
[
'1',
'2',
'3',
'4'
],
[
'5',
'6',
'7',
'8'
],
[
'9',
'10',
'11',
'12'
]
);
I hope this is of interest.

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).
