I've tried out Exercism for a few languages. The tracks that have Learning Mode are the most worthwhile. Raku just straight up doesn't work. The exercises themselves are ok to great but the REAL killer feature imo is the amazing community and the ability to see and compare your solutions. You can request code reviews from volunteer experts for any of your solutions and the volunteers are always really thoughtful and helpful. All for free!
Definitely varies by community. Elixir had the fastest responses in my experience. Often I would get a response within a day or two. F# and Haskell were quite a bit slower, on the order of multiple weeks.
Sounds like it depends on language popularity, although Elixir isn’t all that “popular”. “Loved” perhaps, but not “popular” like C# or JavaScript or Python.
Actually, I've found the Raku community to be most helpful when it comes to understanding the basic concepts of the language. We'd be interested in hearing your thoughts about how Raku doesn't work. Please stop by #raku on Libera.Chat if you are interested in sharing your thoughts.
Sorry about the issue. I'm split between both the Raku and Perl tracks, and don't currently have much time for keeping up on maintenance for either unfortunately.
Please post issues on the Exercism forum if you encounter anything else. I only learned of this issue because someone else spotted this post and reported it there.
I signed up and took a look, and you are indeed correct. _Excorcism's_ lesson plan is broken. Raku is not. I have no idea why they are doing things the way they are, but what they have is not setup correctly. It's a shame. That might have been a decent teaching environment.
I have found better luck using repl.it to test code, and working through the Raku Course at https://course.raku.org/
