APL is a crazy language from the 70s that is sort of an "alternate evolutionary tree" - it's famous for being the original Array-oriented language (which makes it the basis of NumPy, Pandas, Matlab, and anything else that encourages vectorized operations), and for consisting of insane strings of characters (this was before ASCII had been settled upon, so why not have a buncha Greek in there?) http://www.jsoftware.com/papers/50/
