Thanks, this is great and much more meaningful to me than the generic "tool of thought" hype I'm used to. APL is extending scalar functions with implicit map and reduce operators, and doing it in a way that's more general, consistent, and concise than, say, MATLAB or R's system of rules for scalars/vectors/arrays, or NumPy's array broadcasting rules.
