Iterating over more than one array in parallel

In the next example I'd like to show a totally different case. What if you have two (or more) array you'd like to combine somehow? How can you go over the elements of two arrays in parallel?

examples/arrays/z.p6
#!/usr/bin/env perl6
use v6;

my @chars   = <a b c>;
my @numbers = <1 2 3>;

for @chars Z @numbers -> $letter, $number {
    say "$letter $number";
}

Output:

examples/arrays/z.p6.out
a 1
b 2
c 3
