This is indeed a cool project! Happy to see experiments on non-English programming languages. I have one question — not trying to be offensive or doubting, just out of curiosity — does Han make use of the unique properties of Hangul (or Korean in general)? Like, I remember sawing a Turkish programming language on HN the other day, and I might be wrong but my impression was it makes use of some syntax unique to Turkish, and I wonder if Han has similar features. Or, asking it differently, if I replaces only the lexer to another lexer recognizing a different script, will it not work?
