Head on over to https://raku-advent.blog to see this year’s posts so far … thanks to all for the great contributions:

Advent: Last Call for your Participation

We already have 8 days under Santa’s belt with a further 7 posts lined up. So only a few slots left. Don’t miss out and reserve your slot now for the festive fun at the authors.md page before Anton and I grab them all. All it takes to get on the schedule is to make a quick PR with your name and your proposed festive post title(s). Beginner, Intermediate or Genius level – your call.

I am picturing the Advent Calendar as a Raku Iterable – a Seq for example – everyday we will pull one and in the meantime, hopefully you will have stepped forward to claim a slot before we run out of material.

Raku Tips ‘n Tricks

A recent Raku Snippet, shared at https://glot.io, caught my eye. I have reproduced the meat of it here:

role Sortish { 
    method is-sorted(--> Bool) {
        ?self.&{$_ Z<= .skip}.all
    } 
    method is-unsorted(--> Bool) {
        so one $_ Z> .skip with self
    } 
};

my @a does Sortish = [1, 2, 3, 3, 4, 6, 5];

say @a.is-sorted;
say @a.is-unsorted;

This shows just how easy it is to do a mixin in Roles. A video showing this idea in action is also available.

Your contribution is welcome, please make a gist and share via the raku channel IRC or Discord.
