I may want to write a more BASIC scripting language that falls back into Javascript APIs so that IT professionals can write plugins without having to know Javascript to do it. This looks like it was the key I was looking for. How similar is this to ANTLR - which is my only implementation experience with context-free grammars (although I've studied formal languages in uni)?
