Does anyone have an example of a real app (albeit small), all examples I find are in isolation, imagine a simple CLI app that takes arguments of currency pairs java -jar rates.jar USD:EUR USD:GBP GBP:EUR, validated the currencies were valid ISOs code from a hardcoded set and args in correct format, then IO to to fixer.io (simple GET request using fuel or whatever), a retry IO to wrap, and IO to output the list to screen. Further exercise which convienently introduce other monads adding to the same example. Something like this would make things really click for me
