Wandering around on Rosetta Code, I encountered a programming language I'd not previously heard of, Ursala. Here's the main web page for it:
http://www.basis.uklinux.net/ursala/ The first question of the Ursala FAQ is "What does it look like?" The short answer written there: "Like nothing you've ever seen." Don't be too sure of that, though! The third FAQ entry is "Have you ever heard of APL?" That direct question goes unanswered, but, I've seen "iota" in some of the examples so I have my suspicions. The most interesting thing I've seen there so far is the FAQ "Why is function application right associative?" It got me thinking that J must also be "a language that distinguishes notationally between product spaces and function spaces" and that this is an aspect of the departure from lambda-calculus that Backus urged in his Turing paper. -- Tracy ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
