As someone that likes lisp, I enjoyed a lot reading this. My first try when reading about functional programming was to try: Filter(Negate(is.numeric),c(1,2,"hello","bye")) just to receive something unexpected, then in freenode someone answered that c cast types to the more general type, here strings. So I have to begin reading from the beginning about types. I think that Hadley can gives a very sharp opinion about what is needed to transform julia in a better R, if that is possible. Julia is about speed and no so much to make a big community, people use R because there are a lot of packages and is easy to install and well supported. Python with pandas show that you cat catchup is you try. So the question is if julia will receive some strong support or will be always a second rank players, time will reveal.
