# While a package global variable may be visible within all scopes, its value may change depending on localization and assignment:
\!h # The program below starts by declaring an our variable, $scope, as well as three functions.
\!h # It ends by assigning to $scope and calling main().

our $scope;

sub $inner {
  say $scope;
}

sub main { # prints $scope's current value, outer scope, and localizes the variable
  say $scope;
  local $scope = 'main() scope';
  middle();
}

sub middle {
  say $scope;
  inner();
}

$scope = 'outer scope';
main();
say $scope;
