arcfide has claimed on several occasions that non-programmers take to APL quite easily, and can read and collaborate on it with a programmer, be talked through it directly, in a way they can't/won't do for mainstream languages. I find this such an unlikely sounding claim that I want to reject it without consideration, or at least assume that he's only talking to a very restricted subset of engineering non-programmers. APL is decades old and very much a business language by origin in IBM System 360, there ought to be decades of people's experience with this on both sides to back it up or refute it - programmer and non-programmer. Is there?
