Added a lot to the interpreter, but some odd problem where snprintf seems to print the wrong thing something like a 10th of the time. Debugged it for a while over two days, and I've narrowed it down to the actual snprintf call. It seems to happen under some different circumstances for compiled versions too, so I'm just going to keep it like this for now.
