Yes, I did try it. What is missing is probably “why is it designed like this”, because currently I’m trying to match the interfaces while I don’t understand what problem am I trying to solve. These abstractions are “too much” for a newbie.
Also, the currently given examples are too complex - even the one with the chorus. It combines too many moving parts without explaining the motivation.
Of course, I understand some of the problems you are addressing with these abstractions, but probably quite a small part.
The ideal tutorial would be one starting from Sys.argv, then explaining “why do we need this more complex thing” and “why even this is not enough”. I’d be very happy to write it once I grok it.
