Solution: Zip two lists into a hash

Here is a possible solution to the task.

Code

my @names  = <Anna Bob Cara>;
my @scores = 90, 85, 95;

my %result = @names Z=> @scores;

for %result.sort -> $pair {
    say "{$pair.key}: {$pair.value}";
}

🦋 You can find the source code in the file zip-to-hash.raku.

Output

Anna: 90
Bob: 85
Cara: 95

Comments

Z=> is the zip metaoperator applied to the pair constructor =>: it walks both lists in step and builds a name => score pair from each position.
Assigning that list of pairs to a % variable makes a hash, which is then printed in key order.
