One of the problems I've always had with niche languages is that they're so alien compared to my background with scripting languages (Ex: Lisp, APL, Prolog, Forth, Smalltalk, Haskell...etc) and thus harder to figure out how to idiomatically do something.
Btw, there is a neat book for Prolog (black cover) on programming text adventures in Prolog. I found it was the only thing that made it start making sense to me as in how I can start to think in Prolog like I do Python. You might enjoy it as well, but you may be past it by now.
I'll have to check out your Klong code at some point. It might be a nice start for me. I think I know how to pass things around, but I'm sure there are pitfalls to get passed.
Forth might be a good subject for you to cover at some point further in the future too.
Thanks!!
