If they had taken Javascript (or if you prefer a more coffee-script like syntax) and added Go's best features: interfaces-as-duck-typing, channels as fundamental types, string iteration over runes rather than bytes then they would have had a nice little language. The only thing I like is underscore for private variables. Go does the opposite (which I think is a safer approach): anything you want public has to start with a capital. It really works—it is both easy to do and easy to read.
