Dear Dylan-enthusiasts, I recently vectorized MacintoshCL via a set of macros. Now I can say e.g. (+ a b) where a and b may be numbers OR vectors, or lists, or arrays of numbers and the code does the obvious thing. Or I can say (sin a) and if a is a vector the Sine function of all elements will be computed and a vector returned. Since you are working on a language for the 1990ies, where I expect to see more vector processors than today, I wonder whether it would not be appropriate to include vectorizing constructs into Dylan from the beginning. It would certainly facilitate the high-level implementation of many numerical algorithms that can be expressed on the abstraction level of mathematical vectors or arrays. I can provide further information on VectorCL if needed. Cheers Hans-Martin Adorf ST-ECF/ESO Garching b Muenchen FRG
