Division by zero in Raku is one of my favourite topics. Let me demonstrate a couple of approaches that can be used in solving Task 1 of the Perl Weekly Challenge 31.
The task is to write a function that checks the division by zero without explicitly comparing the denominator with zero.

Task 1: List all Christmas days which fall on Sunday in 2019–2100. Task 2: Find all combinations of three numbers, which give 12 in total.

Hello, let us solve the text-processing Task 1 from the Week 26 of the Perl Weekly Challenge. The task is: Take the two words and count all letters in the second word, which are present in the first word.
I have two solutions here, and I believe there is potential to make them shorter.

This is article about programming. This solves Task 1 of the Perl Weekly Challenge 027. The so-called sexy prime pairs are pairs of prime numbers that differ by 6.

Factorial, being a classical task for practising algorithms, is a great example to demonstrate the features of Raku. Let us update the code so that it caches the already calculated values.

This is the Task 1 from the Perl Weekly Challenge Week 17. You have to implement the so-called Ackermann function.
This is an interesting function that is defined kind of recursively but actually this is not a recursion, as the recurrent formula is using the function as an argument of itself.

Task 1. Capitalise all small letters ‘e’ and count the number of replacements in the string ‘Perl Weekly Challenge.’
Task 2. Write a one-liner that, for the numbers from 1 to 20, prints ‘fizz’ if the number is divisible by 3 and ‘buzz’ if it is divisible by 5.

A couple of days ago, Perl 7 was announced.
Isn’t that a great news? Well, yes and no. I have my personal feelings about this but I hope I can also see some other things that are not so much subjective.
