Comma basically chokes on this

[JJ]

It freezes with a notice below saying "indexing... " Haven't waited for it to end, to be honest. This calls for at least one of two optons

1. Include .idea files in this repo (if it effectively ends) so that anyone using it does not need to index it locally.
2. Warn about either long wait time to index it using Comma, or not using Comma in the documentation for this repo, recommending alternatives (I don't know how good is VS Code with Raku at this point in time)
