Or you can make it more generic with recursive code:

use Data::Dumper;

use strict;
use warnings;

my $arr1 = ['A', 'B', 'C'];
my $arr2 = ['foo', 'bar', 'qux'];
my $arr3 = [1, 2, 3];
my $arr4 = ['apple', 'banana', 'pear'];
print Dumper(mix($arr1, $arr2, $arr3, $arr4));

sub mix {
    if (@_ > 2) {
        return mix($_[0], mix(@_[1..$#_]));
    } else {
        my @a = map {[$_[0]->[$_], (ref($_[1]->[0]) eq 'ARRAY') ? @{$_
+[1]->[$_]} : $_[1]->[$_]]} (0 .. @{$_[0]} - 1);
        return \@a;
    }
}

Which prints:

$VAR1 = [
          [
            'A',
            'foo',
            1,
            'apple'
          ],
          [
            'B',
            'bar',
            2,
            'banana'
          ],
          [
            'C',
            'qux',
            3,
            'pear'
          ]
        ];
