Alternatively, you can look at the completely free www.Aplusdev.org, "A+" language that was also created by Whitney.

There is also GNU APL which I have been playing with and has some good ideas also, including the ability to create scripts.

I would like to recommend Kona[1] as well. It is an open-source K implementation, with some small differences.
