@kasdeya To be fair, it seemed to be more of domain specific language. And in that light it makes a lot of sense to develop and run it in a language that is very good at doing those. Not the only example of such a thing. ZIL, the language used for developing Infocom adventures was a Lisp dialect of sorts that compiled to a bespoke virtual machine. And today we have Lua which even the authors admit has semantics similar to Scheme.
