Any new features written or planned?
Absolutely love the idea of arrays and maps. Funny story, I was building an RPG stack with a large world map, and rendering just wasn't fast. Then one day I learned about hashtables/maps, I went home and immediately came up with an approximation in HyperTalk, rendering became nearly instantaneous. I'm guessing folks will need them pretty soon into their scripting experience.
Same for modern iterators, and all the things we now consider basics. If you see a chance, add them. You've got the knack for the language, I don't think anyone here would be offended if it doubled/tripled in the count of things it could do.
