I walk through the development of a utility for auditing Santa's Naughty and Nice lists. Along the way, I introduce literate programming, multiple dispatch, types, type subsets, links to documentation, perl6 collections, and File IO. And, I've been told I managed to do all this without making the reader they've been dragged over rough ground behind a certain festive sleigh.

The key thing to remember when you start learning a Larry Wall Language is that you only need to worry about the parts you need to worry about. It's more like learning a natural language than a programming language. Learn how to say the things that are important to you, and it will serve you well even if you speak with an accent.

  #!/bin/bash
  echo hello

  #!/usr/bin/env perl6
  shell "echo hello"

  #!/usr/bin/env perl6
  unit sub MAIN($name,:$times,:$language);
  say $name, $time, $language

  ./foo.p6 --help

It even has built-in multi-dispatch command-line arg-processing: https://docs.perl6.org/language/create-cli
