Not too much to report. I am getting back into Simply Scheme again. I guess my desire for enlightenment got the upper hand.
I ran into the same issue with the Kotlin koans as I did with 4Clojure: I am just going through the API docs searching for something that looks like it might be the answer. That to me gets really frustrating. I found a site by a guy named Antonio Leiva who will send 30 free lessons to you via email about Kotlin. I will let those pile up and go through those. Kotlin isn’t like Scheme’s R7RS, where you can list all the functions on one page.
