I have implemented a rudimentary Ruby to Javascript converter. So I don't 
think it should be much harder to do the same with Java. Of course as Java is 
static typed, one would need to pass Objects everywhere and do runtime 
type-casting all the time, unless one implements some kind of type inference 
for Ruby (which I think is possible and usable is some situations). So in the 
end, I don't think it would be much faster than Ruby, maybe even slower. 
Well, it would probably be faster than JRuby but much less flexible (as I'm 
talking only about a subset of Ruby, without the whole dynamism Ruby provides 
you with).
