Use array references:

#! perl
use strict;
use warnings;

my @list = ( 'a' .. 'z' );
my @array_chunk5 = _array_chunk5( @list );

print "Array chunk of 5 =\n";
my $count;
print "Chunk ", ++$count, ":\n", join("\n", @$_), "\n\n" for @array_ch
+unk5;

sub _array_chunk5
{
    my @arr = @_;

    if (@arr > 5)
    {
        my   @chunk;
        push(@chunk, shift @arr) for (1 .. 5);

        return ( \@chunk, _array_chunk5(@arr) );
    }
    else
    {
        return \@arr;
    }
}
