I was (pleasantly) surprised by Claude Code doing Raku - also with a limited training set (~2000 Stack Overflow, a bunch of Rosetta, 2,500 modules). I put this down to the quality of the code for the core community who are all frankly uber-gremlins.

Yeah Raku feels so expressive and lovely to me with the help of an AI assistant. I've only done toy programs and scripts with it but it is actually so nice.
