There is no built-in function, but I can give an example. Since you might need to break on different values, this is one place a solution based on a closure might be apt:

#!/usr/bin/perl
use warnings;
use strict;


my @data = ( 1,2,3,4,5,6,7,8,9,10,11,12 );
my @collection = ();

my $break_5 = &break_by(5);

$break_5->( \@data, \@collection );

for my $c (@collection) {
    print $_, " " for @{$c};
    print "\n";
}

sub break_by {
    my $count = shift;
    return sub {
        my ( $data_ref, $collection_ref ) = @_;
        my @temp = ();
        foreach (@{$data_ref}) {
            push @temp, $_;
            if ( @temp >= $count ) {
                push @{$collection_ref}, [@temp];
                @temp = ();
            }
        }
        push @{$collection_ref}, [@temp] if (@temp);
    }
}

And the output is:

C:\Code>perl close_and_break.pl
1 2 3 4 5
6 7 8 9 10
11 12

Update: Tighter code
