Also you may want to look at Bitwise String Operators, and relatively new bitwise operator '|.'.
Here I use v5.28.0:

#!/usr/bin/perl -wl

use strict;

my @array1 = (0, 1, 0, 1, 0, 1, 1, 1, 1, 1, 1, 1);
my @array2 = (0, 0, 1, 1, 0, 1, 0, 1, 0, 1, 1, 1);

my $bits1 = join '', @array1;
my $bits2 = join '', @array2;

print $bits1 | $bits2;

use feature 'bitwise'; # from v5.22

print $bits1 | $bits2;
print $bits1 |. $bits2;

# So...
print "Result: ", join ', ', split //, $bits1 |. $bits2;

Result: 0, 1, 1, 1, 0, 1, 1, 1, 1, 1, 1, 1
