I do have some examples in the examples section. There's a link to the OCaml implementation on the page as well. A repl.it would be awesome, I'll definitely do that.
I hadn't heard of golfscript, but those would make some really great examples. I do have a couple Advent of Code 2019 solutions though.
Thanks!
for boosting popularity:
1- would be nice to use in tryit online or repl.it
2- would be nice to have a link to the implementation repo in the docs
3- have you tried winning some golfscript contests on stack overflow?
4- main improvements over K, with small code samples?
