After some chats with Grue, I'm gonna get the Lua one working first. If there's problems with that, then we can talk about switching to something else.
This project has been inactive for a long time. If anyone is interested in continuing this, I have code that works with circa-Dec-05 verge that parses (almost?) all VC using flex/yacc/treecc, converts it to Lua, and runs it.
As for your suggestion: I like scheme, but I think Lua would be more friendly for, say, error messages. Also, scheme is so scary looking, no one would ever want to use a 3rd party scheme library like might be possible with Lua.
