Problem Statement

If your system has a means to generate random numbers involving not only a software algorithm   (like the /dev/urandom devices in Unix),   then: show how to obtain a random 32-bit number from that mechanism.

Let's start with the solution:

use experimental :pack;
my $UR = open("/dev/urandom", :bin) orelse .die;
my @random-spigot = $UR.read(1024).unpack("L*") ... *;

.say for @random-spigot[^10];
