Notes
Starts in approx. 1sec (as measured on an M1 MacBook, takes longer on first run).
For LLM::DWIM features, you will need e.g. a free of charge ChatGPT key and go
export OPENAI_API_KEY=mykeygoeshere.Currency exchange rates are provided as at the installation date, reinstall crag (
zef install App::Crag --/test --force-install) to refresh them.crag is a full Raku repl - so you can write subroutines, loops, conditionals, comparisons and so on (see https://docs.raku.org)
If your calculations outgrow the crag app, you can use the underlying crag modules in Raku code.
