Perl6: loading functions into another namespace

Question

I want to use Perl6 modules to group some functions that I often use. Since these functions are all related to each other, I do not like to add them to the class.

I like the idea usewhere you can choose which functions to import, but I don’t like that the imported functions are then stored in the global namespace.

For example, if I have a file my_util.pm6:

#content of my_util.pm6
unit module my_util;
our sub greet($who) is export(:greet) {
    say $who;
}
sub greet2($who) is export(:greet2) {
    say $who;
}
sub greet3($who) is export(:greet3) {
    say $who;
}

and file test.p6:

#!/usr/bin/perl6
#content of test.p6
use v6.c;
use lib '.';
use my_util :greet2;

greet("Bob");    #should not work (because no namespace given) and also doesn't work
greet2("Bob");   #should not work (because no namespace given) but actually works
greet3("Bob");   #should not work (because no namespace given) and also doesn't work
my_util::greet("Alice");     #works, but should not work (because it is not imported)
my_util::greet2("Alice");    #should work, but doesn't work
my_util::greet3("Alice");    #should not work (because it is not imported) and also doesn't work

I would like to call all functions through my_util::greet(), not just through greet().
