Cool! Having a parser generator written in JS that outputs a parser in 
JS for a compiler that outputs JS is a very nice idea :)

I didn't like the coffee script syntax very much though, especially the 
python-style handling of whitespace. But the way to define functions was 
nice! What I'm looking for is more like standard JS but with syntactic 
sugar, like:
	var foo = (x) { x*x+123 };
instead of
	var foo = function(x) { return x*x+123; }
and some array stuff like maybe (0..9).do (x) { print x };

I found another parser generator which I managed to modify and got it to 
work with seed: http://jscc.jmksf.com/
