Solution: An our variable

Here is a possible solution to the task.

Code

package Config {
    our $port = 8080;
    my  $secret = 42;
}

say $Config::port;
say $Config::secret.defined;

🦋 You can find the source code in the file our-variable.raku.

Output

8080
False

Comments

1. our $port becomes part of the Config namespace, so it is reachable from outside as $Config::port, printing 8080.

2. my $secret is lexical — private to the package block — so it is not in the namespace. The path $Config::secret finds nothing, an undefined value, so .defined is False. This is the difference our makes.
