Rosetta Code is a community site that presents solutions to programming tasks in many different languages. It is an excellent place to see how various languages approach the same task, as well as to get a feel for the style and fluent use of each language across a variety of domains.
Raku is well represented on Rosetta Code (though we always welcome new submissions!); there are well over a thousand Raku solutions as of early 2021. Here are a few ways to find what you're looking for:
Rosetta Code itself keeps an up-to-date alphabetical list of tasks already solved in Raku; you can find this in the lower section of the Rosetta Code Raku category page.
Rosetta Code's category collection is weighted towards language names, tasks whose solutions where too long and had to be split onto multiple pages, and so on. To make it easier to find the tasks you're interested in, here is a shorter category list, with links directly to the Raku solutions:
These tasks and solutions were nominated by members of the Raku community as our favorites -- perhaps because the task fits our collective whimsy, or because the solution struck us as particularly beautiful. Here then, in no particular order, are the entries that -Ofun for us:
A 2D cellular automaton simulating fires and forest growth, with 木 trees and a touch of color for the fires.
A simple task of finding the last Friday in each month of the year, with two brief solutions: an imperative one in the style of several other dynamic languages, and an impressively short functional solution using classify and Whatever blocks.
