I frequently use 13 : to explore different ways to express an idea. Here's one I just tried, as part of something else: 13 : '(,x) i. y' ] i.~ [: , [
This does not seem any simpler to me. What is the benefit of recasting the expression like this? Does it optimise better at run-time? Is "13 :" trying to minimise the parens at all costs? If so, why? ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
