Hey all, I'm posting this to HN to see if there's any interest in a full-fledged JavaScript port to Lua. Colony right now is a proof-of-concept, but there might be a real use case out there for embeddable JavaScript where solutions like V8 would simply be too large.
Since it's a source-to-source compiler, you can use Colony generally wherever Lua source is required. For example, I was able to follow the beginners tutorials of the Corona SDK (http://www.anscamobile.com/corona/, a cross-platform mobile SDK that uses Lua) by programming CoffeeScript instead, which was surprisingly fun.
