Yep - interessantes Interview. Apropos "quite boring":

$ cat quicksort.p6
#!perl6
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;

$ ./pugs quicksort.p6
12345
