I'm very happy that you are checking out my code! There were multiple reasons that broke the quicksort example, chief among them being that "map" and "grep" had not been implemented. :-)

However, if you check out the current repository, you'll find an example/quicksort.p6 that indeed works, using "multi sub" dispatch. I'll list you in the AUTHORS file, if you'd let me know your name.

The code in the repository looks like this: 

use v6;

multi sub quicksort ( ) { () }

multi sub quicksort ( *$x, *@xs ) {
    my @pre  = @xs.grep{ $_ < $x };
    my @post = @xs.grep{ $_ >= $x };
    (@pre.quicksort, $x, @post.quicksort);
}

(1, 5, 2, 4, 3).quicksort.say;

I need to check with p6l folks on whether quicksort() can match a slurpy list this way. It is possible that quicksort( *[] ) would be a more accurate. Once I found out the answer, I'll fix the examples accordingly.

Thanks,
